Control the power settings for a USB hub

hubpower's Issues

THANK YOU! :-)

it works very well!

OS locks up after issuing a command

Very serious issue.

I believe I just tried a power off command and my USB ports are currently power cycling (about 0.25s on then 0.75s off). The power cycling is only on the hub which I tried to control, not the onboard USB ports (they're fine).

Additionally, when I try to issue another hubpower command, my entire OS locks up.

I'm on a Raspberry Pi with Raspian for what it's worth.

What's the license?

Cool bit of code - would like to use some of it - what's the license?

Does this support USB3.X? If not, how hard is it to add support for this?

Am I the idiot?

Hello - I downloaded hubpower.c and compiled with:
gcc -o hubpower hubpower.c - and it compiled ok.
Here is what I get when I use it:

Seems to always give me the help menu
