Public bug reported:
When plugged, the adapter does not work (NM does not found any LAN for
example) on gutsy, kernel 2.6.22-11
dmesg result after plugging:
[75716.967241] usb 5-1: new high speed USB device using ehci_hcd and address 9

lsusb result for this adapter (there is no other wifi adapter plugged):
Bus 005 Device 009: ID 148f:2573 Ralink Technology, Corp.
A workaround to make the adapter work is to unload the rt2500usb and the
rt73usb modules, then just reload the rt73usb module. Then, dmesg result:
[75894.074919] usbcore: deregistering interface driver rt2500usb

At this time, NM find wifi network can connect to these networks and it
works...
