• Hey, there everyone.
  Can anyone give a link to a thread that explains the function thoroughly of a USB memory drive when it communicates with a PC?
  Thanks

• The USB spec is freely available here: http://www.usb.org/developers/docs/usb_20_110512.zip
  
  It's highly non-trivial, especially if you want to think about partitioning, filesystems and any other layers on top of USB - but even USB itself is a pretty complicated system.
  
  USB in a nutshell is the best overview of the bus I've seen, but it barely scratches the surface of how an actual device functions.

• Check out Travis Goodspeed's projects.  His current one is emulating flash drives in software using a sort of USB spoofing device he built.  His stuff is really interesting.  The youtube videos of his conference talks are great too.
