Hi Alan, Do you think the SYBA hub (Genesys Logic, 05e3:0606) is that bad?
I tried TEAC (Trek Technology, 0a16:9005) sticks, which work fine in the SYBA hub, and also another unknown brand (0204:6025), which worked fine also in the hub. What is very strange also, if I write data to the stick (if it works), it seems to work better after that, that's why I also thought of the residual bytes.
