Front usb ports have stopped working.
So my front usb devices (there are two) have stopped functioning properly. On the front of my case there is a usb/audio panel (audio part is fine since its connected elsewhere), and a flash card reader which also has an extra usb port. Each device is connected to a seperate USB header on the motherboard (MSI-RS480 if it helps).
My flash card reader used to appear as 5 different drives in explorer, now they are missing. I first noticed the problem when i inserted a flash drive and got a "usb device has malfunctioned" pop up in XP
The ports will sometimes give me a device has malfunctioned error, and sometimes they do nothing at all. They still seem to be supplying power though, flash drives will light up, as will my optical mouse. All ports on the back of the computer and my pci card work perfectly.
So what I've done so far is uninstall all my "usb root hub" entries in device manager and reboot allowing windows to reinstall them, i got back where i started, all but the front ones work fine. I also dual boot vista, so I booted into vista and have the same problem, so that leads me to believe this is just a hardware problem. I disconnected and reconnected the two devices from the jusb headers on the motherboard and rebooted and again, back where I started. I've made no significant hardware changes or even opened the case recently to have caused this, so I'm rather puzzled.
Any Ideas what I should do?
