: It means you have an inconsistent tree.  The first number is the oldest

Yes.  Of course I have local modifications, but none in the usb stack.
But I've also done a svn update from the top of the tree multiple
times and this version number persists.

Not entirely.  This flash has worked in this computer in the past
without issues (like a year ago when we were first integrating hpsusb
into the tree).  This flash is plugged directly into the computer.
This behavior is consistent across multiple ports on the computer (so
it isn't a bad port).  While this doesn't prove it isn't a power
issue, the odds are stacked against it being one.  If there were a way
to get the internal hub to tell me how much power it can deliver, and
for me to query the flash to see maximum current draws, we could see
if we're close to the edge or not...
