Public bug reported: After updating to the latest kernel, a USB Hub/switch that used to work has a problem. It works initially when booting up my Linux Mint system, but if you switch the USB over to another PC and back, all my Linux Mint PC's USB ports all stop working. It is an IOGear GUS404 usb 2.0 sharing switch and is not using external power. I've tried plugging in a separate USB keyboard to make sure this is the case. Hope this helps.
