Hi,

coming from https://lore.kernel.org/all/20200818041324.GA3173@Susan/

as I understand UAS was working for JMicron JMS567 in the past, then was
disabled in the kernel, now using usb-storage.
Why? The hardware should support UAS and does so on Windows. Before 5.4 it was
working with UAS on Linux as well.

I purchased a 5-bay USB enclosure "ORICO DS500U3" but UAS is not working:

External USB 3.0 20170331000C3)

    |__ Port 5: Dev 8, If 0, Class=Mass Storage, Driver=usb-storage, 5000M

Aug 28 18:47:09 [mtp-probe] bus: 4, device: 8 was not an MTP device

With a mdraid raid0 and 5x1TB discs I get only about 72MiB/s to the raid0 which
is really slow. UAS could do more.

Is there any chance UAS could get fixed for that device in the future? At least
is seems to have worked someday with older kernels?

Best regards,
Massimo
