Turn off "USB root hub"/device power
-
Hi everyone, I'm trying to turn off a USB device power, theoretically, the USB spec states it is possible. On Intel chipset disabling the "USB root hub" will cut the connected USB devices power, I know that with Ali and Via chipsets (and probably others) its not the case.. the device will enter sleep mode instead. The only thing I've been able to find is restart, disable-enable, and changing the max allowed power consumption. None of the above did the trick.. before giving up completely I wanted to hear your opinion of this.. Do you know a way to Turn off a USB device power? Thanks, Ariel.

Set the max power to zero?

Set the max power to zero?
From my understanding it will not necessarily turn off the device power.. its more like a “recommendation for the hub. (i.e if a device claims its max usage is 10ma but you use 100ma it might disconnect the device) I'm willing to test it again (on several computers) if you’ll point me to a working test application..
