Wireless USB Adapter DWL G122 not detected by ural(4)

Your device is not supported by ural(4).
The ural driver supports adapters based on Ralink first
generation 802.11b/g wireless USB adapters (RT2500USB).
Your adapter is based on the new RT2501USB chipset which
requires a new driver because the MAC/BBP is very different.

Thanks to a patch made by Sam Leffler [1], the adapter is now detected
with ural(4) but is not working (tested on HEAD and RELENG_6)

and no access point is detected

with wpa_supplicant also:

Thanks for your help.
