"This feature request is to add a new "mode" to BlueSCSI that allows it to connect legacy SCSI devices to a modern-ish host via USB. [...] The scope of this issue will be to add basic mass storage support (hard drive, cd-rom) to BlueSCSI on a Linux host."
Maintainer of BlueSCSI here - this is really early/gathering info to implement, but glad there's interest! If you have one of these adapters and would like to help out please check the details in the ticket.
