I can't find a BIOS setting to keep the USB ports powered on suspend. Wondering if Ubuntu can keep them alive? I just want them powered so some devices (phone) attached to the ports can carry on charging while Ubuntu is suspended (I don't care about battery drain - the laptop is normally plugged into power).

    What color is the plastic part inside the port ? Black is USB2, blue USB3 and yellow is Suspended-powered ports usually, which are determined by BIOS settings

  • The port I'd like to keep powered during suspend is blue (USB 3). Any way?

Strange, it seems it does stay powered after all, but the particular device I had plugged in just had to be unplugged and replugged (while suspended) in order for it to continue charging. More of an issue with the device I had plugged in and not Ubuntu or the laptop then. Thought I'll mention this here in-case someone asks the same question in future.
