There is no /dev allocated to the disk drive when plugged into the USB3 board.

Typing “dmesg | less” and looking for ‘usb’ shows the following

This appears to be happening during a reboot.  There was no disk plugged into it at the time.

I’ll plug in a disk and test it next chance I get, if you think it will help.

I get the following

It appears to have a the xhci_hcd driver.  Does that help?
