My USB4 SSD enclosure arrived, in good news the usb3 fallback works well and I get 10gbit on normal usb ports. Also good it shows up as USB4 in boltctl, in bad news it doesn’t work in USB4 mode XD.
Update: Weirdly enough it works when daisychained through my expu enclosure, but seems to be limited to 20Gbit for some reason, topping out at 1.7GB/s.
Not sure if that’s a framework issue or a me buying the cheapest one I could find on aliexpress issue though.
