The main issue was finding a driver that worked. I will try the official
driver again with with an old Windows XP that I have.
Perhaps running in a VM is causing some issue.
The device I have didn't come with its official driver disk unfortunately.

The SCSI Enquiry info has some strange entries in it. Perhaps I will post
the diag output for that.
Since it is identifying itself as an 1800u I did worry that it had a custom
firmware or that someone had bricked it by loading incorrect firmware for a
different device.

Cheers,
Ralph
