Thanks for replying.
I hope these sets of patches ameliorate all of the unplugging and rmmod'ing for the rt2800usb/rt3070.
And yes, I know the rt2x00 project does not cover staging drivers, actually the staging driver adopted by Ubuntu (and others) is in fact rt2870sta and not the rt3070sta (from Ralink), but they both do not allow switching between them and rt2800usb.
On my system, when rt3070sta is loaded first and then subsequently rmmod'ed to modprobe the rt2800usb the following error occurs:

then the system freezes, partially, meaning for example I cannot issue simple "ifconfig" - this command as well as other commands are inactive. To unlock the system, thus command prompt and so on I have to unplug the device, then dmesg basically is flooding with errors.

Now trying vice versa rt2800usb --> rt3070sta:
Interestingly, when rt2800usb is first loaded and then rmmod'ed without unplugging followed by loading of the rt3070sta takes about a minute or so, but the rt3070sta becomes operational. But not always. A repeat of the procedure partially froze the system again.
Tried with both staging rt2870sta and manually compiled rt3070sta - the result is the same, total or partial system failure, forcing me to plug/unplug the USB chip.
