Subject: [Cerowrt-devel] using a usb3 hub as a hackerboard power switch?
Date: Wed, 27 Apr 2016 11:44:01 -0700	[thread overview]
Message-ID: <CAA93jw68U4YYup6Jy0sRTo1z4n+47Q+w8nzPs18ee2Wy4SfvtA@mail.gmail.com> (raw)

I am curious if there would be a way to use a powered usb3 hub to
individually be able to address and power cycle the ports individually
on it?

I have accumulated enough hackerboards powered via usb that it would
make sense to just power them all that way... kind of like I already
do with these:

and just use that (rather than an individual power supply for each).

 I am perpetually locking one up or losing connectivity to it for some
reason or another.

I figure somewhere in the usb spec/protocol/device driver/whatever
there would be a simple command to just flip the power on and off to
the port....
