How to control external usb cooling fan

[bpidskalny]

Hello

I am trying to control an external USB cooling fan threw EG. Does anyone know how I can trigger the power on and off to a specific USB port. I can turn it on and off manually threw device Manager in the control panel. Any help would be appreciated.

Download utility devcon from Microsoft.

Then, use it as follows: List all known USB devices:

devcon find USB*

Disable USB device:

devcon disable "USB\VID_xxxx&PID_yyyy"

Enable USB device:

devcon enable "USB\VID_xxxx&PID_yyyy"

now i have not used this personally but as to wether is will actually power the device off all depends on hardware as well ad drivers and some other things, you may have to even add a reg line for each item you want to control, to allow for a selective suspend kinda thing.

roll the dice and see if it does what you want, then adding it to EG to just trigger a command line program is really easy
