Hello,
I'm using an Ubuntu smartphone connected on one of the USB ports to my
netbook as a router to the Internet. I wanted to power-off the USB port to
a) save energy in the netbook and
b) not having the phone always charged for the memory effect in the battery.
I tried:
$ usbconfig
...
ugen0.3: <AquarisE4.5 BQ> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
(500mA)
# usbconfig -d ugen0.3 power_off
# usbconfig -d ugen0.3
ugen0.3: <AquarisE4.5 BQ> at usbus0, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=OFF
(500mA)
as you can see the state is now pwr=OFF, but in this state the USB port
is not longer usable. What is the correct way to shutdown the 5V
provided via USB to the device?
Thanks
matthias
