It's a 10-port hub from RSHTECH (RSH-ST10C). Output of uhubctl for the USB 3.2 part: Current status for hub 4-1 [0bda:0423 TerraMaster 4-Port USB 3.0 Hub, USB 3= .20, 4 ports, ppps] Port 1: 0203 power 5gbps U0 enable connect [2109:8822 VIA Labs, Inc.

USB3= .1 Hub 000000001, USB 3.20, 4 ports, ppps] The strange thing is, powering off port 1 and 4 works, but power 2 says it's powered off, but the LED indicatior on the hub is still on (usb drive bay doesn't suspend, the other 2 do). Now i don't know if it is a hardware or a software bug. How to find out? Ca= n it be fixed? --=20 You may reply to this email to add a comment.
