Bug#584945: linux-2.6: 0bda:8172 Realtek USB WiFi unsupported
 
Package: linux-2.6
Version: 2.6.34-1~experemental.2
Severity: normal

This device should be supported (at least it says that on the cover, and
supplied driver, which does not compile anymore).
It is detected, but then returns: unknown rf chip, can't set channel map
in function:rtl819x_set_channel_map() in dmesg

Seems to be a related problem to the recently fixed #580740
The device gets an interface, but no rf signals seem to be detected
(compared to a wifi card next to it, right next to the AP).

Full dmesg output is:
[ 996.420056] usb 3-2: new full speed USB device using uhci_hcd and
address 7

The hardware vendor seems to have lied to you.

Please send the supplied driver and I can try to puzzle out what the
important change is.

[...]

That's an entirely different problem - the driver did not claim the
device ID for a device that it could handle. Here we have a device that
it can't handle.
