| 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 |
