Thanks! > E
with hogs, you cannot enable/disable. This is the reason why this topic got stuck in the first place. On ath79, it seems that usb_power is only used for external USB ports so far. So I felt that the discussion led about toggling USB on ramips would not apply here, and that choosing gpio_hogs over a user-space solution would be preferable for this case. With any new device support for the last 6 months, USB ports were set up with gpio_hogs IIRC. Best Adrian
