Brr.. Could you give some kernel debug info & coldsync debug info
on this?

When doing the USB 50x port, I just ignored this kind of stuff
and it got right eventually. To me it looks like USB Snoopy really
tries to be too smart and rearanges its output a bit.

This is the start of the SLP protocol; so the Sony CLIE emulates a true
Serial device; i.e. you should look at the Visor USB code rather than
at the Palm 50x USB code: the bulk transport speaks SLP protocol.
