I have usb 2 and USB 3 pendrive with me , when i checked powerconfig -energy it says my USB Hub cannot be suspended. I assume that my usb Pendrives supports selective suspends.
There is posibilities that uSB device cannot be suspended if any unsupported USB device is connected to the same HUB.
So i am using only USB pendrives (USB KBD/Mouse are not connected) still power config fails to disable USB Device.
How would i know my USB device supports Selective suspend? If it supports any settings i need to change in system?
It would be helpful for me if i can clear this problem
Thanks for your support in Advance
