The UAS mode of Norelsys NS1068(X) is reported to fail to work on several platforms with the following error message:

And when trying to mount a partition on the disk the disk will disconnect from the USB controller, then after re-connecting the

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.

A quick internet search shows various problems with this device even under Windows, so yes this seems like a good idea:

The NS1066 chip from the same vendor seems to also suffer from this problem (its USB ID is 2537:1066) according to the report of Armbian community. However I don't have such device (I have a USB HDD
enclosure
with USB ID 2537:1066, but it doesn't report UAS function at all; as it's
If it has been reported to not work in uas mode then I think adding the same quirk for the 1066 device-id is a good idea, can you please submit a patch for that?
I don't have such devices, although as Armbian suggests the 1066 device needs also to be blacklisted.
Maybe we can wait for an unforunate NS1066 user to add the 1066 ID.
