That's not right -- at least, it's not right for the first copy of the 
trace that Steve sent out.  (I didn't look at the second copy so maybe 
it's different.)  In the trace I saw, the first Get-Device-Descriptor asks 
for 64 bytes, not 18.  Also, note that there's a port reset in between 
that request and the following Set-Address.
