HighSpeed Hub Bus 003 Device 066: ID 0518:0001 EzKEY Corp. USB to PS2 Adaptor v1.09 Strangely enough, they are almost the same. I can see the printer listed in both, for example, which is connected to the hub; yet, the printer does not work in the first case. Neither does the keyboard, but I don't know which device in the list the keyboard is. @jsalisbury may yo explain why on earth you marked this as incomplete?? ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1250488 Title: USB hub stopped working on a given USB port (would work on any other port). Reboot fixed the issue Status in “linux” package in Ubuntu: Confirmed Bug description: I have two USB ports that I usually use interchangeably: to port A I connect the mouse, to port B I connect a USB hub (to which I connect a keyboard, printer and other devices). Suddenly (probably after resuming from a suspend), the USB hub stopped working when connected to port A. It would work fine, however, if connected to port B. When I say the hub stopped working I mean that any device (even a keyboard) wouldn't work if connected through the hub. I exchanged ports dozens of times and 100% checked that: - mouse and keyboard would systematically work fine if connected directly to any of the ports A or B - the USB hub would systematically work fine only if connected to port B - the USB hub would systematically fail (i.e. no device connected through it would ever work) if connected to port A Now I've rebooted, and everything works as expected again: the USB hub always works fine whether I connect it to port A or B. I thought this was something physical until I rebooted and found out that everything works again. This is absolutely ridiculous.
