I use lubuntu (light ubuntu :-)).
I spent a long time trying to get the module parameter to work but I 
couldn't so I modified the grub command line and it used usb_storage. :-)

/etc/default/grub
GRUB_CMDLINE_LINUX="iommu=soft audit=0 usb_storage.quirks=0bc2:ac30:u"

$ sudo smartctl -d sat -a /dev/sdc
smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.13.0-39-generic] (local build)

GRUB_CMDLINE_LINUX="iommu=soft audit=0 usb_storage.quirks=0bc2:ac30:"
I think it is using UAS but how do I know it is not using NO_ATA_1X?
It seems to work for smart but I'll put it back in case it has bugs.
