Hi all,


I'm currently having an issue where no USB ports nor laptop touchscreen are working.  In Device Manager, USB xHCI Compliant Host Controller has a yellow triangle-exclamation mark over it.  The device status is:  "This device cannot find enough free resources that it can use. (Code 12).  If you want to use this device, you will need to disable one of the other devices on this system."




I was attempting to install a USB hub.  All devices connected to the hub were working EXCEPT my HDMI monitor.  I started fiddling around in Device Manager with the USB devices -- disabling them, un-installing them, trying to update drivers, etc.  So I certainly screwed something up.


What I've attempted so far.


1.  Uninstalling all USB devices,rebooting, and disabling USB devices in the F2-BIOS. Rebooting, re-enabling F2-BIOS, rebooting, etc.

2.  Using the Intel Driver Update Utility to detect necessary drivers. Then downloading and installing those drivers.

3.  Attempting to manually download and install the USB 3.0 eXtensible Host Controller.  This resulted in the following error: "This computer does not meet the minimum requirements for installing the software".


Machine details:

* Windows 8.1 Pro with Media Center, x64

* Inspiron 7537


Let me know what additional information I can provide. 


Thanks for the assistance.

Conflicting drivers possibly I/O problem.  Make sure you have all the other drivers poperly updated like the Chipset Driver, and the Graphics card as in go to the website and manually install the latest version I also would recommend Drive Booster.  Try uninstall PCI Bus and allow all devices connected to reinstall on its own.  I heard possibly it could be an ATI graphics driver issue.  Last resort flash the bios.  Can you give more detail on the specs of your computer like the model number, if you dont know mobo and card.
