unsupported TL-WN422G (0cf3:1006)

Hi!

I've bought TP-LINK WN422G USB wireless card with Zydas chipset (as
stated by the seller) in the hope it will be supported by zd1211rw
driver (listed here [1]), but it seems it's not.
I've tried to find help on linuxforums.org <http://linuxforums.org> [2]
— the only open option is to use ndiswrapper, which (a) is reported not
to work earlier in the thread and (b) is the last option for me to
consider. Search in linux-wireless's archives yielded only a result [3]
with a patch included in my kernel (Ubuntu-2.6.31-14.48).

My card's vendor:product id is 0cf3:1006 (different that the one listed
[1] for WN422G).
If i execute the following after plugging the card:
echo "0cf3 1006 FFFFFFFF FFFFFFFF 0 0 1" | sudo tee -a
/sys/bus/usb/drivers/zd1211rw/new_id

dmesg reports (notice the 5s interval between first and second entry):
--------------
[21745.628183] usb 2-1: reset high speed USB device using ehci_hcd and
address 9
[21750.776294] usb 2-1: read over firmware interface failed: -110
[21750.888072] usb 2-1: reset high speed USB device using ehci_hcd and
address 9
[21751.085403] zd1211rw: probe of 2-1:1.0 failed with error -110
--------------

lsusb reports the card as
Bus 002 Device 009: ID 0cf3:1006 Atheros Communications, Inc

What I can do to better diagnose the problem and possibly get the card
working?


best regards,

If you take a look at the vendor's windows driver for TP-LINK WN422G *v2*,
it becomes obvious that the device does not use the ZyDAS zd1211/ Atheros 
5007UG cipset, but has switched to the new Atheros AR9271 chipset (which 
technically is a 150 MBit/s 802.11n "lite" chipset family) instead.

%ATHER.DeviceDesc.9271% = ATHER_DEV_9271.ndi,     USB\VID_0CF3&PID_9271
%ATHER.DeviceDesc.7010% = ATHER_DEV_7010.ndi,     USB\VID_0CF3&PID_7010
%ATHER.DeviceDesc.1006% = ATHER_DEV_1006.ndi,     USB\VID_0CF3&PID_1006

At this moment a new driver called ath9k_htc is under (early) development:

Hi, Stefan!
Thanks for your explanation!

OK, I found this section on the CD with the drivers but my product id is
1006. How do you know it's AR9271 chipset and not, say, AR1006?
I found /AR9271/i on the CD in driver files for Windows 2000, XP, XP64.
Vista driver files don't have this substring anywhere (they have '9271'
in netathur.inf 6 times, and '1006' is 6 times in analogus lines as well).

 

    At this moment a new driver called ath9k_htc is under (early)
    development:
           http://wireless.kernel.org/en/users/Drivers/ath9k_htc


If i understand correctly 'Status' section, this driver is wireless and
radioless at this moment, right?
Maybe I should check this driver to see if it recognizes my card correctly?


best regards,
Piotr

Which means your device is TP-LINK WN422G v2 - and therefore AR9271.

Disclaimer, I neither have access to an AR9271 device, nor am familiar with
its development state, therefore I base this on the afforementioned driver
wiki page and the reference code.

It's not merged in 2.6.32, wireless-next (~= 2.6.33) or wireless-testing 
yet and http://wireless.kernel.org/en/users/Drivers/ath9k_htc#Status is 
pretty explicit about its state, namely that it doesn't actually transmit 
any data yet. Even though development seems to be pretty active and showing
quite some potential, it will likely take several months before it becomes 
enduser compatible.

Hi, Stefan!

Thank you for all the help!

Unless i will be able to exchange my card with one based on zydas
chipset and if i will have some free time, I'll contact ath9_htc
developers (or the wiki) for any further reference and/or testing.

Funny think about this USB card is that, when I plugged it into my
laptop, it made my broken broadcom PCI-E card work again immediately, so
money was not lost completely :)

Best regards,
Piotr
