Today I'm trying to figure out which driver is best for my USB wireless dongle. Everywhere I look I just see Ralink STA but this isn't telling me which module this actually is.

I'm sure there's a way of looking it up but the computer should be able to tell me, shouldn't it?

Meta: This question is open to any piece of hardware, not just my wireless card. It would be helpful if we had a thread of useful diagnostic procedures so that other people can find out what's going on with their hardware.
