I have a problem with some USB/PCI usb audio hardware I am using on my APU. It seems a software reset (e.g. reboot or reboot -h) is not enough to clear problems that occur and the only way is to power ONOFF.
Is there any way to initiate that from within the APU in software? Or can it be done through GPIO add on? I need to be able to do this remotely so can't flip the power.
