The same shit, it seems like p54usb doesn't provide support for this Corega 
wi-fi stick. If you'd have done modinfo p54usb you could see that there's 
no corega's vendor and device code among available aliases, the only one 
Corega device listed is 07aa:001C (your Corega WLUSB2GTST has device id 
07aa:0020), but it uses different ISL chip.
