Title: A10 USB power control
Post by: hexcode on April 28, 2014, 08:02:19 AM
Hi all,

The product specs say that there is USB power control on the 2 USB Host ports, but I didn't find much documentation on these.

How are these controlled within Linux?  Is there something I can toggle to turn off power to a port, and turn back on?

Furthermore, are the data lines for the USB port deactivated as well?  For some USB devices, having powered data lines without USB power will damage the device.

Thanks!
