we have per-endpoint directories already. Why don't you dump endpoint
debug info there? Also, while at that, could you write a patch that
properly decodes the queue sizes? It looks to me as the queue sizes are
in same units as GTXFIFOSIZ registers

shouldn't the print be done with locks held?

why is this necessary? Seems like it would be nicer to create a
directory structure if the current operating mode is host so that we
don't need to write anything.
