usb power cycle

[giorgio franchini]

hi,

i need to hard reset an usb device that random freezes; there is a way to force a reset power cycling usb 5v aux?

how to use usb_ena output signal?

i tried using sys/class/gpio exporting gpio129 but nothing.

best regards

giorgio

No that is not possible using gpio. The components for USB ena are replaced by 0 ohm resistors. You can use the rtcwake command in Linux in combination with a powerdown. But to enable the wakeup you need to patch the kernel. Check the archives of this mailing list, i have posted the patch approx als year ago.

Regards Erik
