[OPiOne] USB power off
Hello friends!
I Am using 3G modem(Huawei E171 connected by OTG cable) on my OPi One for internet, but one problem - modem after few days working freeze. Reboot don't help because not full power off on USB, and after reboot i don't see modem in /dev. Only after physical remove modem and install again it's initialized and work fine.
Question: Can i power off USB from cli?
