disable power to a usb hub?
Hey guys, I've got my carputer running off an MSI wind book. When I put it into sleep mode it barely even lasts for an hour. I figure this is because the USB hub that i have all my usb devices (bluetooth, gps, soundcard) plugged into is drawing power from the laptop and not the external power cable plugged into it. I found this out by unplugging my the power from the hub and the devices still worked 100% fine. Also I put the laptop to sleep with no usb devices plugged in and it lasted 24+ hours. My work laptop can goes 3+ days in sleep mode with no problem.
So, that being said, is there any way to tell windows not to allow power to go to the specific usb port? So that they HUB is forced to power my devices and when power to the HUB dies so do the devices plugged into it. Also how can i tell which port in the device manager is my USB hub. The only usb port that i want to have power going to in sleep mode is the touch screen so that i can wake it up when i power the car on (I found out how to get this working).
