Hello,
I recently put together a new system using the Lian Li PC-9F case that features USB 3.0 inputs on the Top Panel. My motherboard is an Intel branded DH67CL that has 4 USB 2.0 internal headers. There are 2 USB 3.0 inputs on the back of the board. The case comes with a USB 3.0 to USB 2.0 adapter for uses such as my situation.
The Problem is Windows 7 doesn't recognize the USB and I keep getting "USB unkown device" error message when I insert a small USB drive. The error is also listed in the Device Manager under - USB Root Hub (2 ports) -->Generic USB Hub (8 ports) --> Unknown Device. Sometimes when I reinsert the USB flash drive, Windows attempts to install a driver but then it fails and it tells me that it's an unkown device and it doesn't know what drive it needs.
I am sure I'm not the only one that has faced this issue, but I can't seem to be able to find a similar problem on the net or on any forums, including Intel's. (Lian Li does not have a forum that I am aware of). I do not wish to run a cable from the front ports to the 2 back USB 3.0 inputs. I do need them for external HDD.
If anyone have any ideas on how I might resolve this issue, I would apreciate it. Thank you.
Mike
