3.2-stable review patch. If anyone has any objections, please let me know.


From: Maia Kozheva <sikon@xxxxxxxxxx>

commit fd7b9270120ca7e53fbf0469febe0c68acf6a0a2 upstream.

D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a
Ralink chipset supported by the rt2800usb driver. Currently, to work
around the problem (it's missing in all present kernel versions,
up to and including 3.7.x), I had to add this to /etc/rc.local:

echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id

After that, the device works without problems. Been using it for over
a week with no bugs in sight.

The attached patch is trivial and simply adds the new USB ID to the
list of devices handled by rt2800usb.
