HP Wi-Fi Direct Mouse on Linux

In my last post I took apart an HP Wi-Fi Direct mouse based on the OZMO2000 controller from Ozmo Devices.

OZMO based devices are officially supported on Windows 7 platform only, rendering them completely useless as nobody uses Windows anymore… right? Well, it turns out most of the code to use them in Linux is already in place, just waiting to be enabled!


https://fabiobaltieri.files.wordpress.com/2013/02/hp-wifi-mouse-linux.jpg

Wi-Fi direct support in Linux is quite young and still considered as experimental, so read on if you dare to try!

OZMO Devices: Theory of Operation

OZMO controller uses Wi-Fi Direct (a.k.a. Wi-Fi P2P) for communication with the host system, so a Wi-Fi Direct Linux supported card is the only hardware requirement.

Wi-Fi Direct itself is a relatively recent extension of the 802.11 standards to allow Wi-Fi devices to associate and communicate between themselves (point-to-point) without requiring a dedicated common AP but also without the need to disable the existing traditional Wi-Fi connection. This is implemented using an additional “virtual interface” that acts as a software access point (P2P-GO) with WPS push-button client support.

Once the P2P-GO interface is up and running, the mouse can be connected using the WPS push-button scheme: press the soft-button on the host and the “connect” button on the mouse that will automatically associate with the first available AP.

As the device is connected, the real fun begins: as the mouse starts transmitting data to the host using a specific Ozmo’s in-house developed USB over Ethernet protocol, registered to ethertype 0x892e.

Quoting IEEE’s eth.txt:

892E         Ozmo Devices

A protocol to enable USB type data and USB type commands to be sent
between two devices connected by an IEEE802 link, typically an
IEEE802.11 link. The protocol allows encoding of all information
that would normally be present in a wired USB request, such as
request_id and rcode along with payload data. Defined header
structures allow correct delivery of the required fields. The
informaion provided through the protocol enables USB like behaviour
to be implemented between wirelessly connected
devices. www.ozmodevices.com

Sounds complicated? This is actually quite ingenious, as it allows a gadget designer to implement an USB Class protocol, so that once the device is associated and the “virtual USB hub” is installed the actual device-specific protocol can be handled by the already existing USB device-class driver.

Thus, the only OZMO specific code to be installed by the user is the actual virtual USB hub – backed on the Wi-Fi Direct interface. The good news is that the Linux driver is already here, silently laying in the staging/ozwpan directory of modern kernels… Ozmo itself made it, well done Ozmo!

So, how do we use it?

Kernel

First thing we need is to make sure that our Wi-Fi device supports Wi-Fi Direct, which you can tell by running the iw list command and searching for P2P entries between supported interface modes, as in:

# iw list
Wiphy phy0
[...]
        Supported interface modes:
                 * IBSS
                 * managed
                 * AP
                 * AP/VLAN
                 * monitor
                 * P2P-client
                 * P2P-GO
[...]

In this case I’m using an Intel’s Advanced-N 6205 mini-PCIe card. If you are using an iwlwifi based card, make sure your kernel has the CONFIG_IWLWIFI_P2P option turned on, as that enables the experimental P2P support for the driver.

Check with:

# zcat /proc/config.gz |grep P2P
CONFIG_IWLWIFI_P2P=y

The other thing you need from the kernel side is the ozwpan driver, built as a module. Just verify that the module exists, but don’t load it yet, as you need to bring up the Wi-Fi direct interface before:

# modinfo  ozwpan
filename:       /lib/modules/[...]/ozwpan/ozwpan.ko
license:        GPL
version:        1.0.13
description:    Ozmo Devices USB over WiFi hcd driver
author:         Chris Kelly
parm:           g_net_dev:charp

Userspace

Once your kernel is good to go, you need a version of wpa_supplicant with P2P and WPS support. Again, this is quite recent so check if it’s already there with:

$ wpa_cli help p2p
Selected interface 'wlan0'
commands:
  p2p_find [timeout] [type=*] = find P2P Devices for up-to timeout seconds
  p2p_stop_find = stop P2P Devices search
  p2p_connect <addr> <"pbc"|PIN> [ht40] = connect to a P2P Device
  p2p_listen [timeout] = listen for P2P Devices for up-to timeout seconds
[...]

If wpa_cli does not list any supported commands, you want to get a new wpa_supplicant version, so just grab the latest one from git://w1.fi/srv/git/hostap.git and build it using defconfig as a base. Make sure to turn on these options beforehand:

CONFIG_WPS=y
CONFIG_WPS2=y
CONFIG_READLINE=y
CONFIG_AP=y
CONFIG_P2P=y

Once you are done, reconnect your main connection with the new wpa_supplicant using the nl80211 driver and cross your fingers. Still online? Go ahead then!

Pairing

To connect the Wi-Fi Direct device without disrupting the existing connection, we want to create a new interface in GO mode:

# wpa_cli -i wlan0

Interactive mode

> p2p_group_add
OK
<3>P2P-GROUP-STARTED p2p-wlan0-0 GO ssid="DIRECT-3G" freq=2437
   passphrase="sDv0YD4F" go_dev_addr=8c:70:5a:xx:xx:xx
> quit
# iw dev
phy#0
        Interface p2p-wlan0-0
                ifindex 19
                type P2P-GO
                channel 6 (2437 MHz) NO HT
        Interface wlan0
                ifindex 4
                type managed
                channel 6 (2437 MHz) NO HT

Finally, start wpa_cli on the new interface, run the wps_pbc (for Push Button Client) command, and press the “connect” button on the Wi-Fi Mouse. It should eventually go like this:

# wpa_cli -i p2p-wlan0-0

Interactive mode

> wps_pbc
OK [press the button on the mouse for ~1s now]

[...]

The mouse is now continuously reconnecting to our host searching for its USB-over-Ethernet driver. To make it happy just load the ozwpan module, specifying the name of the new interface:

# modprobe ozwpan g_net_dev=p2p-wlan0-0
# dmesg
[...]

That’s it! The mouse is connected and registered with the standard HID driver, just like a standard wired USB device. Congratulations, you’ve made it!

You can also check the existing connection with wpa_cli:

That’s more or less how the basic thing works. The process is still complex for the casual user but all the pieces are in place.

    Hello.
    Your post is realy useful. I’m expecting to buy this mouse, and if you answer on a few my questions – it will be great.

    – how this mouse will work in a place with a lot of wifi hotspots around?
    – it is possible to use it through 5 ghz if my laptop support it instead of 2.4 ghz?

    Thanks.

    • Hi Dmitry,

      thanks! Anyway, keep in mind that the whole p2p-wifi thing in linux is still quite preliminary and experimental. Expect crashes! :-)

      As of your questions:
      – for the hotspot, I’m not sure how things like on-air collision avoidance are handled (if handled at all), but I suspect that as your mouse is going to stay just next to your laptop/PC, it may just go over any other interfering signal easily (it should be all about signal/noise ratio) – that’s just a suppositions, through, as I use the mouse home and there are not many APs here.
      – as for the frequency, I guess it should work just fine, if your main connection uses a 5GHz channel, the mouse is going to use the same frequency.

        Fabio.

        Thank for your reply.
        I don’t mensioned previously and would like to clarify that i’m using windows 8. Laptop is asus zenbook ux32vd.

        In my appartment i usualy find about 20 hotspots on 2,4 ghz (as connection in my wifi router) and i afraid that there will be an interference using this mouse.

        So if i make up my mind to buy it, for sure i’ll post a comment here.

      • Err… I’m quite sure that I’ve read somewhere that this mouse does not work in Windows 8 (yet…), so maybe you’d better ask in the HP forums for that.

        If you discover something for interference… drop a comment!

        Thanks,
        Fabio

    Nice guide, compliments, I have just purchased an hp x7000 wi-fi mouse and I have a Pc witch ubuntu.
    The problem is that I am a newbie and so I can do a very few things, can you help me? If you want you can send me an e-mail.

    P.s. Tutto come sopra, sono italiano se vuoi parliamo in italiano, la mia mail la vedi giusto?
    Se riuscissi ad aiutarmi te ne sarei molto grato, anche perchè il mouse è costato un po e mi dispiacerebbe non usarlo.
    Grazie mille

    • Hi Marco,

      unfortunately it appears like your wi-fi interface does not support P2P operation, so there’s not much you can do apart from waiting P2P mode to be implemented for your specific card. Can you tell which wi-fi driver are you using? You can find it with lspci.

      • Hi Marco,

        so that should be the Ralink RT3290, and it seems that there is no P2P support in the kernel right now. The good news is that the driver seems to be based on a generic Ralink library, so it’s not unlikely that P2P would be added in the future, but there’s not much you can do now.

        Fabio

    thanks for answer, but i haven’t understood everything so well, it is an hardware or software problem?
    The PC it is an Hp Envy 17, was running win8 and the mouse worked, now i have installed ubuntu and how can be possible that the hardware doesn’t support the mouse anymore?
    here there is the whole output of iw list, in the last lines there is written P2P and P2P client.

    • That’s a software limitation, it just means that the functionality has not been implemented (yet) in the Linux driver.

      • Marco says:

        Ok thanks, when do you think i will be able to use it?
        Thanks forma answer

      • Hard to say, but it looks like the driver is maintained by the community, so I would not exclude that, but it could easily take a year or so. Even iwlwifi P2P implementation is still considered experimental…

      • Marco says:

        I understand, it’s a pity, i have spent 50 euros, i just have to wait, switching to windows only for the mouse isn’t worth..or not?

  5. Mark says:

    Hi Fabio, nice and clearly written guide, however I have been stuck for hours at the ‘> p2p_group_add’ part. My wpa_cli responds with the error message ‘UNKNOWN COMMAND’, even though the command is listed when I use ‘# wpa_cli help p2p’, I confirmed that several times.

    lspci returns:

    04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 03)

    Do I need to change to the nl80211 driver and how do I do that?

    I am on Ubuntu 13.04 and also own the HP Wi-fi wireless mouse.

    Hope you can help me out.

    Bye,

    • Hi Mark!

      The error seems to indicate that the version of wpa_supplicant you’re using is built without p2p support, you may have to build from source with a custom config. Beside that the PCI device you listed is a wired network card so you are looking at the wrong one! :-)

      • Mark says:

        Hi Fabio, thanks for the answer. I did build wpa_supplicant from the latest source. Maybe it went wrong because I did make && make install two times. The first time I forgot to manually edit the config file before building. The second time I used the custom config settings that are recommended in your guide. Maybe some things got mixed up? However, I have no idea how to completely remove the built from source wpa_supplicant, so I could start again with a clean install. And thanks for noticing that I looked at the wrong device ;-) I will check it again tonight.

      • Hi! Running make install twice is not a problem, it will just overwrite the files. Check what’s in /usr/local, your stuff built from source should be there, separated from the one you install with the package manager.

    Ok, there are some wpa files in usr/local/sbin. I will leave them for now. I just realised I have my wifi on a usb dongle, so of course I had to run lsusb instead of lspci… ;-) I’m such a noob. It returns:

    Bus 001 Device 004: ID 0cf3:1002 Atheros Communications, Inc. TP-Link TL-WN821N v2 802.11n [Atheros AR9170]

    I’m pretty sure the Wifi Direct support is there. I’m guessing the problem lies with the driver, because every step in your guide goes smoothly except for the part where you write to change the main wireless connection to the nl80211 driver… I don’t know how to do that… Could it be that’s why the command p2p_group_add fails in the next step?

    I appreciate your help very much.

    Mark

    • I just realized I missed the part where you mentioned wpa_cli help in your original post! :-) So, my guess would be that you are running the correct version of wpa_cli against the default version wpa_supplicant, so you have the command listed in the client but it’s not understood by the supplicant, hence it returns UNKNOWN_COMMAND (referred to the actual wpa_cli -> wpa_supplicant control command). One other explanation is, as you suggested, that you are running with the wext driver, and that returns a “command not impelemented” error that may be confusingly mapped as UNKNOWN_COMMAND.

      In both cases, I don’t know how to tell NetworkManager (that’s what I guess you’re using on your ubuntu) to change the driver, but you may test the whole thing manually by:
      $ killall NetworkManager # or maybe: service network-manager stop
      $ cd /usr/local/sbin
      $ ./wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf # you need a manual static configuration here

      The above command runs wpa_supplicant manually, and -D sets the driver.

      At this point you can try to fire up wpa_cli and send the group add command again. To get back connectivity just kill wpa_supplicant and restart NetworkManager (or reboot).

      Good luck!

  7. Mark says:

    Well, I’m still totally lost. I have removed wpa_supplicant and re-installed again. But many things go wrong during building now. I have version 2.0, so that’s the right one isn’t it? Also I don’t know how I could update my wpa_cli, I can’t find any information about that online.

    Some lines I get back from make && make install:

    […

    /usr/include/netlink/socket.h:57:14: note: expected ‘struct nl_handle *’ but argument is of type ‘struct nl_sock *’

    […]

    ../src/drivers/driver_nl80211.c:8483:2: attention: passing argument 1 of ‘nl_socket_get_fd’ from incompatible pointer type [enabled by default]

    […]

    /usr/bin/ld: cannot find -lnl-3
    /usr/bin/ld: cannot find -lnl-genl-3
    …]

    Another evening gone ;-) I will report back if I make any progress. Thanks again!

    • Well, if it can help I remember wpa_supplicant to be quite hostile to build from source most of the time! :-)

      Anyway, I’ve always used some random git version, if it does not build you can either try to change the config or go back in time with the revisions… Good luck with it!

  8. Mark says:

    Hi Fabio, one more question. I built from source because I know how to do that, but not (yet) when things start to get more complicated ;-) I have been searching for a beginner’s guide to git on the web, but it looks scarily complex to me. I just want to get wpa_supplicant up and running, not learn everything about git because I’m not a developer myself (far from it). So how do I install wpa_supplicant from git without getting into too much detail? At this point I made a clone of the repository from git://w1.fi/srv/git/hostap.git and now I have no idea at all what to do with it or where it is on my hard drive…

    • Hi Mark, after you did the clone you should have a copy of the last sources in a directory where you ran the command, from there you build like the normal distributions. Just try the latest version, it may just works.

    Olá Fabiobaitieri.
    Como instalar o HP Wi-fi em uma máquina com Debian?
    Obrigado pela atenção
    Robson

    • Hi Robson!

      I don’t really know if Debian has anything that helps, such as some repo with a fancy version of wpa_supplicant or something else… but the instructions on the post should be distribution agnostics, so just build from sources!

    You can install?

    • If your question is if it looks like it has P2P support, the answer is no, just compare the output with what I posted, P2P stuff should appear in “Supported interface modes”.

    Hi, could you help me with making this same mouse work on windows 8 64b?
    Is there any chance of doing some modification on the driver for win 7 64b (wich is the only one you can download from the HP web) to make it work on win8? I would really apreciate it!

  12. alex says:

    How to add this to autostart on system boot?

    • Hi! That may be a bit tricky, wpa_cli command can be easily scripted (just run wpa_cli ), but I think you want to run those after the normal wifi connection is up, so you may need something more than just some line in rc.local or whatever your distro is using. Sad note: I’m not using this anymore since Intel dropped p2p support from iwlwifi on newer kernels. :-(

    any ideas? ubuntu 14.04 lts

    thanks in advance

    • Well the wifi part seems to be fine… did you load the ozwpan driver (with the right parameter)? You could try unload and reload it just in case… you should at least see the virtual usb hub created by the driver.

      • sjalvete says:

        uhm. sorry, lol. i entered p2p_wlan0-0 in ozwpan. now everything works just fine (unlike windows, where it used to lose connection every 15 min or so). now do you by any chance have an Idea how to do it with a shell script?

      • sjalvete says:

        ok, sorry again, i read the comments and found out my question was a dupe. if i come up with something, i will post it here

    Dear fabio,

    I am trying to set up my mouse hp wifi

    Everything is fine till I enter the command p2p_group_add:

    P2P-GROUP-REMOVED p2p-wlan0-0 GO reason=REQUEST

    maybe the CONFIG_IWLWIFI_P2P is not enabled in my kernel but I don’t know how to check it and how to change it.
    I am running ubuntu 14.04.

    Thank for your help.

    Tug

    • Hey Tug, that’s awkward… sounds like a bug, you should try rebuilding wpa_supplicant from git. About the kernel option, don’t waste time looking for it: it has been dropped together with its code in recent kernels. :-( That part is not going to work anymore in iwlwifi… I think it’s going to be supported in newer Intel chipset only.

  15. Denis says:

    hi,
    im trying to install my hp wifi mouse in fedora 22 and im stuck at having the ozwpan drivers built as a module. im cloning the git repository that has the drivers which seems to be a clone into the kernel. is this the right way??

    • Hey Denis, the driver seems to be only distributed with the whole kernel so you probably want to grab the kernel source for your distro if you don’t want to replace the whole kernel just to have the module… I don’t really know how to do that for Fedora though. One alternative would be to repack the mainline module as an external module, which should only involve creating a new makefile for it.

      • Actually, do you still need all of this? I just tested the mouse (after years :-) on an Ubuntu Trusty LTS something and it worked without any custom kernel, the module was already installed as well, I just had to do the wpa_cli stuff… yay! :-)
