Hi all
I have in my hands a multi bay SATA enclosure, with some unidentified
SATA multiport but using the JMicron JMS567 USB to SATA bridge.
This bridge is known to support UASP but in this particular
implementation, due to something weird/buggy (most probably the
firmware) doesn't who up as UASP capable, in fact a lsusb -t shows no

The vendor, Orico, claims explicitly that the enclosure shall support
UASP. But without the bInterfaceProtocol 98 the device is not bind to
UAS driver. So the question is: is there a way to forcibly bind a
device to UAS?
