viewtopic.php?t=316455&sid=b178ded7db92 ... db85efc53f
I am using a Isy Box IB-3740-C31, seting up a NAS with my RPI4. When the RPI4 was new, I never sorted this out, so I gave up and used an old PC instead. Now this power consumig PC finaly gave up, so I´m doing doing another new try.

The problem I have is that file transfers are going terrible slow since my RPI4 is not using USB3 UASP.
RP4 indentify this USB3 device as USB2 of some reason, I really dont anderstand why, and it works faboulsy on a PC with igh speeds.Any Ideas?
