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.
