No, you can use a modified ASPI driver under windows or a modified
wine scsi driver to dump every packet. I explained it more or less
into details in a mail some time ago on this list. However it is
extremely boring and gives random results.

You have been introduced to the main problem of the linux driver
writer : clueless manufacturers. You may try to lie by telling you are
writing a driver for windows, or you are a potential very important
customer needing linux support, or whatever reason, but that may not
work... I am currently contacting braille displays manufacturers to
write drivers for a project of mine: some are very interested, some
really don't care and wouldn't give their (uninteresting, poorly
designed) protocol for all the gold in the world.
