Matt:

Look at Daniel St�ckner's posting:

http://sourceforge.net/mailarchive/forum.php?thread_id=2842723&forum_id=5398

He's using UHCI, and the drive fails with a Babble error on the very first 
data transfer that's more than 64 bytes long, which coincidentally is a 
MODE-SENSE transfer.  The log indicates that 64 bytes were received, 
indicating that the device tried to transmit a packet over the 64-byte 
full-speed limit.  That seems to imply that it really doesn't like the 
MODE-SENSE for some reason, although it worked just fine on the initial 
8-byte MODE-SENSE.

Can you think of any way to fix this?  Since the caching information is 
right near the start of the page, do you think it might help to request 
just the first 16 bytes or so, rather than the first 128 bytes?  It turns 
out that the full page length is 1536 bytes -- don't ask me why.
