Z68 Chipset USB driver problem

[drob182]

My USB 2 ports both on my motherboard and the front panel header stopped working a few months ago. They still give power but aren't properly detected in windows. Anything I plug in shows up in windows as malfunctioning. In device manager I can see that the chipset pci express driver is installing and configuring fine but fails to launch.

 

My pcie nic and gpu (gtx 660ti) work perfectly fine as do all my usb 3.0 ports although those have a separate controller from the usb 2 ones. I tried reseating both pcie cards in case they are the source of the problem but no improvement. Haven't tried running the pc with them completely removed but plan to soon. Other things I've already tried are updating drivers for the devices that aren't starting properly in device manager, downloaded and installed every possible driver for the motherboard and cpu, removing the overclock on my gpu and cpu, looking for bios settings that might be applicable (legacy usb support), and using a different header for the front panel usb 2 ports.

 

I have no clue why this is happening, the usb 2 ports worked properly when I first built the pc back in july. Anyone have experience with a problem like this themselves or any ideas what's going on or where I can go from here?

 

Is there any chance it's the cpu? I currently have a 2500k installed but I'm upgrading to an e3-1230v2 in the next week or so.

Zero chance.

 

Does it do this with a fresh install or a Linux live distribution?

Haven't tried those yet, I'll dig up one of my live usbs and check momentarily

Booted manjaro from a usb 3 port and it worked initially with my keyboard and detected my usb bluetooth dongle as a bluetooth dongle but when I tried to start bluetooth or connect the usb dongle for my wireless mouse they all stopped working. I'm going to try another mouse and keyboard with nothing else plugged into the usb ports and see if that helps but I'm starting to think it's the motherboard hardware, is that what you were leaning towards too?

Only the front ports, or are the rear ones affected as well? I'd suspect the case ports/wiring first, if not, the motherboard.

Front and the rear ones on the motherboard as well. In both cases the usb 3 ports work but usb 2 give power only. I've tried three different headers on the motherboard for the front panel but saw no difference, haven't tried booting with it totally unplugged yet though.
