HP Envy Touchsmart E0K45UAR: Envy of HP Touchsmart E0K45UAR USB Controller Driver

Hello

Computer details:

HP Envy Touchsmart E0K45UAR

8.1 Windows Professional x 64

I have a USB controller, who decided to uninstall itself this morning and I'm unable to get it working again. This was noted during the user's usb keyboard stops working, but the keyboard and the standard touchpad work very well. I can't get any other USB periphials to work on this computer.

The Windows Device Manager shows "other devices / Universal Serial Bus (USB) Controller" with a yellow exclamation point icon.

Hardware ID:

PCI\VEN_8086 & DEV_9C31 & SUBSYS_190E103C & REV_04
PCI\VEN_8086 & DEV_9C31 & SUBSYS_190E103C
PCI\VEN_8086 & DEV_9C31 & CC_0C0330
PCI\VEN_8086 & DEV_9C31 & CC_0C03

I tried to remove the controller device manager USB, then picking up Windows to automatically reinstall USB controller drivers, it did not help.

Logs of events coming from the activities of this morning show the following:

I'm sure that there is a problem with the drivers, but I can't find the USB drivers on the HP support page for this model of computer downloads.

Thanks in advance for any help.

So I just ended up doing a restore system since a couple of days and I have my USB controller online.

No idea of what was actually wrong with it.
