USB Mass Storage traces for Windows XP

These traces were collected using the Bulk-only transport, with protocol 
x06 (Transparent SCSI) and x05 (SFF-8070).  For each protocol there is a 
trace for non-removable medium, removable medium (-rmb), and medium not 
present (-no).  I used a different Product ID for each protocol and 
removable setting, so the results should be independent of each other.

Some things to note:

	Unlike Windows 2000, Windows XP does use MODE SENSE for page x08.  
If it's safe for XP it ought to be safe for Linux, provided we always ask
for 192 (0xc0) bytes.

	Windows XP does use the PREVENT-ALLOW MEDIUM REMOVAL command.  
Oddly enough, it only used the command during the tests where no medium
was loaded -- that doesn't make any sense.

	When faced with removable medium, Windows appears to poll once a 
second to make sure the medium is still present.  I don't know how it 
would react if the medium were to be removed; one would think there 
wouldn't be much Windows could do about it.
