Bug Description

Several atmel-based USB wireless adapters do not work with at76c50x kernel driver, now the only one since at76_usb was removed from /staging in .32. Previous workaround was to blacklist at76c50x so the system would fall back to at76_usb, which works. It no longer seems possible to compile at76_usb from source (http://at76c503a.berlios.de/) against .32 or .33

There only way to can get wireless working in Lucid is to use the 2.6.31-rt and blacklist at76c50x as before. The errors I see when using at76c50x with the Netgear MA101b are:

[ 924.409976] wlan0: deauthenticating from 00:x:x:x:x:x by local choice (reason=3)
[ 924.416951] wlan0: direct probe to AP 00:x:x:x:x:x (try 1)
[ 924.611261] wlan0: direct probe to AP 00:x:x:x:x:x (try 2)
[ 924.811260] wlan0: direct probe to AP 00:x:x:x:x:x (try 3)
[ 925.021261] wlan0: direct probe to AP 00:x:x:x:x:x timed out

With the same firmware, AP, WEP key, the a76_usb module (in 2.6.31) works fine. Just a heads up that Lucid will not support a whole host of Atmel USB adapters at this point. See also: http://ubuntuforums.org/archive/index.php/t-1280956.html

Hi eval-,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Jeremy,

I moved to Europe for work and have not had time to download the upstream kernel and test it, but I have contacted a developer (who is subscribed) and he confirmed the issue. You may close this bug if you want, because the problem is clearly upstream (at76c50x_usb does not work and at76_usb has been removed, plus it no longer compiles on .32+), but I highly doubt it is fixed in any current .32 or later release. Although I cannot (yet) speak German, I can see others are having the same problem:

To be honest, I took the same solution and simply bought a new card because I did not have time to work on this. But regressions are always a bit sad.

Hi, I'm the upstream maintainer of at76c50x-usb driver. I can verify that the driver is indeed broken upstream, a mac80211 change broke the driver. Unfortunately I haven't found the time to fix it this yet. Sorry about this.

Slightly OT and somewhat late: I only became aware of this problem when I upgraded form debian lenny to squeeze, advancing from kernel 2.6.26 to 2.6.32. I found out that the at76_usb sources from the latest kernel.org 2.6.31 staging tree compile happily against 2.6.32, too (using the Makefile from berlioz), and the driver works for me (blacklisting at76c50x-usb). With some kludge, it can be made to compile against 2.6.38, but I haven't verified its functionality yet. If there's interest, and if I find that it works, I'll post patches here.

eval-, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
