matteo sisti sette, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (2.17). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-2.17 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - 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: Incomplete 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.
