Posting here so people can shortcut the journey I went on to solve this
Nice enclosure on the whole, except for one issue around powering the chipset that controls the USB to SATA bridge
Code: Select all
ID 174c:3074 ASMedia Technology Inc. ASM1074 SuperSpeed hub
ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge, ASM1153E SATA 6Gb/s bridge
Which means if you attach this to a Raspberry Pi or some mini pc (N100 etc) solution, you can get errors like the following under heavy io (particularly between disks in the enclosure)

I've put a power USB hub between my mini pc and the enclosure and I have had no resets since, with Debian 12 kernel 6.1 UAS and no quirks, with smart pass through. Everything working as expected
Hope this helps someone!
