Subject: [PATCH] Add support for 2001:3c1e (D-Link DWA-125 rev B1) USB Wi-Fi adapter

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

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.
