External SSD not recognised

Hi Tim,
I digged around for the adapter and found this:
https://git.kernel.org/pub/scm/linux/ker...0c279a3fe9

My adapter chip seems to have mounting problem:
"The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:
xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip."

The solution seems to be a linux source code change.
I have no programming skills. How do I go about it?

In the meantime I have followed the raspbian update command and formatted my disk as MBR, exfat, which
is still processing.

Thanks & Regards,
Kay
