Sample rate up to 200KHz for the scope (8MHz for logic analyzer).  USB
scopes always seem to be lousy that way.  If they'd just put a lot of
memory onboard and use the USB for viewing rather than real-time
recording, it could be a lot better.

  While I have the hardware people's attention, what uses does the debug
