I don't think that a USB drive can directly record keystrokes. The 
communication goes in the opposite direction that the USB drive would need.

A malicious USB drive can also listen the data going to other USB devices on 
the same controller. You cannot detect this.
Well, your second point is exactly that. As USB is a Bus, all devices should be able to record the other devices messages - and thereby the keystrokes.....
