[SOLVED] Alienware 17 R2 Touchscreen not working

For anyone that has this issue, I did a little digging and was able to resolve this. I did a little digging in Device Manager after being unable to find my touchscreen in the list and found a USB controller that had somehow become disabled. Once I re-enabled this controller the touchscreen along with about 10 other devices repopulated in Device Manager and a quick test of the touchscreen and other features showed that the device was working as expected.

The USB Controller that controls all these devices, that had somehow been disabled is:

USB Root Hub (xHCI)

Device type: Universal Serial Bus controllers

Manufacturer: (Standard USB HUBs)

Location: on Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)

Along with the touchscreen reactivation this device listed many other "HID-compliant' devices that were missing while this device was inactive.

As my issue is resolved I welcome an administrator to close the thread however it would be nice if the thread was still accessible to anyone who has a similar issue in the future as I was not able to find any information about my issue or this possible cause.

Thank for the post. Restarted my laptop, touch screen USB ports and Bluetooth not working or be found. Found the USB controlle, enabled it and everything works now.
