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 goal is to emulate a device similar to this:
image

The scope of this issue will be to add basic mass storage support (hard drive, cd-rom) to BlueSCSI on a Linux host. (Linux seems to be the least picky about USB device drivers). Initial implementation will keep the CDC (console) port over USB to allow debugging. MacOS 9 might not handle composite USB devices properly, so we may need an alternate config for that.

Once this basic functionality is implemented, the following wish-list will be evaluated:

Help Requested

If you have any of the USB->SCSI bridge devices, if you could, plug it into a Linux/Mac host and run sudo lsusb -v and add the output to this ticket. We may need it later when trying to improve compatibility.

this is Akai Mesa II which runs on os9 and connects to Akai xl series samplers
there is also a windows version.
