Turning on and off usb power

Sun Aug 19, 2012 10:58 am

Hello everyone,

I have some usb problems, and nothing helps except disconnect and reconnect.
I was wondering there's a way to turn off and on the power by software.

I've found this (should be pretty straightforward): http://stackoverflow.com/questions/1163 ... on-and-off
But the level options are missing.

Is there something missing in the kernel?
Who is more experienced and can help me with this.

Thank you!

Are you running with a USB powered hub?

A lot of issues are solved with this option. ;)
Noob is not derogatory the noob is just the lower end of the noob--geek spectrum being a noob is just your first step towards being an uber-geek ;)

If you find a solution please post it in the wiki the forum dies too quick

I't a bluetooth dongle (tried multiple with same problem)
Current is about 60 mA when transmitting. Power adapter is 2,5A from a D-Link router, and also tried other sources.
