19:06 topi` is there a way to disable usb +5V power on a certain usb port on the Hummingboard?
19:07 topi` I tried something like this:
19:07 topi` echo "1-4.4.4" > /sys/bus/usb/drivers/usb/unbind
19:07 topi` (substituting a correct usb enum) .. but it doesn't turn off the +5V, maybe just signals a "shutdown" but my USB device is a dumb one which just checks the existence of +5V
19:20 rabeeh those are gpio signals from the processor to the current limiter
19:21 rabeeh '0' shuts it down and '1' powers the usb vbus up
22:38 topi` thanks
22:38 topi` it seems they are at gpio (3,22) and (1,0) in the old HB.
22:39 topi` so, those are gpio86 and gpio32 if I'm not mistaken
