I connected an external Pluggable USB3 external drive doc to a USB3 port on the T440.

It is recognized by the Unassigned Devices plugin.

I click Mount, and after several minutes an error message appears.

See the log below.

The USB drive was working normally when removed from a Windows system.

I re-mounted it under Windows and did a CHKDSK /F which completed without errors.

Do any of these log entries make sense to anyone, and point to the root cause of the failure?

Looks like a USB UASP problem, you can try with the old driver, post the output from lsusb -vt with the device connected

Unless I am missing something, this has nothing to do with the Connect plugin.

I'll move that to general support.

I have worked around the problem by connecting the drives to the USB3 controller that is passed-through to the Windows VM. The drives mount and function perfectly from within Windows.

Next time I have a USB3 drive connected to a non-passthrough drive under Unraid control, I'll post the output from lsusb -vt
