[Bug 580783] [NEW] AWUS036H doesn't work after resume

Sat May 15 01:39:55 UTC 2010

Public bug reported:

System is a Thinkpad T410 with 6050 series chipset (no microcode yet) so
external ALFA AWUS036H wifi adapter is being used.  Ubuntu version is
10.04 with 2.6.32-22-generic kernel.

Adapter works fine until resuming from a suspend (opening the laptop
lid).  At this point a reboot is required to get the adapter working
again.  Bug report was filed from the pre-suspend state, but post-
suspend diagnostics will be attached.

Possibly key dmesg lines (after resume):

Also noteworthy is that lsusb stops listing the adapter after resume.
