Yes, it looks like that one might be affected, it is probably based on
the same platform. I tested (and still have) an 8A.

No, sorry, no time to test further. I don't think I saw any options in
the BIOS of the mobo I was testing with. It seemed like a pretty bad
USB3 problem (or interaction with the firmware and/or hardware in the
8A). The interface was recognized fine, but any attempt to use it would
hang the driver and require a reboot. This was perhaps a month ago or
more, maybe there is newer Motu firmware. Also, this was on 4.9.11-rt9,
newer kernels might have this fixed (or might be worse :-)...
Best luck!
