How enable USB charging when PC switched off?
I would like to enable USB charging when the computer is switched off (I want to charge a DAC with battery).
The computer is a dual boot ASrock 3D Vison with Asrock App charger installed (in Windows)
I have already disabled S5 in Bios.
However if I shut down from Linux my DAC is not charging.
Some suggestions?

Re: How enable USB charging when PC switched off?
I have tried to use the little script in the link to find the address of my usb device. The result is this:
Bus 003 Device 003: ID 20b1:3008 XMOS Ltd
[FOUND] 3-1.1So, if I understand right the directory is "/sys/bus/usb/devices/3-1.1/power/"
Inside this directory there is "level" with value "on" and autosuspend with value "2"
I don't have any idea how this (or other files) should be changed...if this is the right path...
