power for usbhub over otg port
this is likely a very old and re-asked question...
I noticed while trying to get a USB3 powered hub working on my OTG port that it's powering my up-board. As in supplying enough power that it still runs when i turn the up-board's power brick off... Is this OK? it wont cause any damages? no clashes?
