Command to turn off USB from bash.

[wojtek_b]

I have a script, that should turn off the usb power (i need to turn off smog-meter, in order to preserve laser). It should actually work in a way, that turns on, measures, turns off and waits for the next iteration. The code used I believe on A20 is:

/usr/bin/sunxi-pio -m PH26''

however it does not work on H2+ 

Any suggestion, what would work?

No, not PH26, but PH6 on Olimex A20.

 

But on OPiZero, the USB1 has not a switchable power, only USB0 which is switchable on PL2.
