I have a USB wireless card (inside fit-PC2i) which says this in lsusb
Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp. RT2870 Wireless Adapter
I am using Debian. If I blacklist rt2800usb and let rt2870sta do its magic, the interface works perfectly in managed mode. But if I blacklist rt2870sta and use rt2800usb, the interface is there and looks good, but never does anything - no scan results, no nothing, not a single packet received. I have tried this with Debian 2.6.32-4 kernel and experimental 2.6.33 kernel. I have also tried this with the firmware in firmware-ralink package (4KB size) and from RT2870_LinuxSTA_V22.214.171.124 package (8KB size). No combinations of those work.
I'll include some details

I am trying to get the rt2800usb driver working as the rt2870sta driver seems really ugly and I also need AP mode, which that driver didn't seem to support.
It seems many here have gotten quit a bit further with rt2800usb, so I'm wondering what I'm doing wrong...
I updated to compat-wireless as of 2010-04-22, and the rt2800usb driver works!
I even managed to get hostapd working in non-encrypted mode - but my WPA2 troubles are only configuration errors.
However, I was unable to get multiple BSSID support working. I can get the primary BSSID added, but adding a second BSSID always fails.
I updated hostapd from 0.6.10 to 0.7.2 and things worked out a bit better.
I was able to get both WPA2 and WPA working, although for some reason the handshake was only handled once after a hostapd restart - reassociations consistently failed.
Also, I was able to get multiple BSSIDs started in hostapd, but it wasn't without troubles. First of all, I had to change my network card mac address, since it was an odd address. After this, only the BSS that got the original hw address was working and all others were non-functional. Also, beacons were not reliable.
The only reliable setup so far has been just one SSID and no encryption at all.
I will keep on testing...
