btw, keeps happening on 14.04. It may happen randomly on any of the two usb ports I use. Once one port "dies", I cannot connect the hub on that port (but I can connect a keyboard or mouse directly) so I have to switch ports. After a few suspends and resumes, it may then happen that even the second port "dies", meaning the hub won't work connected to that either. At which point I'm forced to reboot if I want to connect the hub.

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.
