I will look and test this (or adapt your) line as soon as I get in front of my machine. I have seen that the corresponding "usb-port" provides a usb3-hub and a usb2-hub, so I think I have to reset both? Are those hubs independent? I will re-check my outputs which I had sent here. Can you add an example-line to the "help-text" when invoking usbreset with no (or wrong) device-filename argument?
