USB reset at Olinuxino micro

[robert.w]

Hello

i am working at project with olinuxino micro and USB 3G modem.

 

From my experience i sometimes i need hard reset modem (turn off,turn on from USB connectro)

 i see that power is controlled by USB1-DRV (PH6) and USB2-DRV (PH3)

 

I try to manually set this pins (PH6 and PH3) to LOW and after some time HIGH level to turn off and on power on USB connectors but this pins i see isn't configured as normal GPIO pins.

so i have error in pyA20 - that this pins aren't GPIO.

I ma a hardware guy so i have only a little experience in programming

 

Can anybody help me with this ?

 

Best Regards

Robert
