Front USB ports don't like USB2?

Hey, weird problem. I have an old Chenming (Antec knock off) dragon style case with the 2 front USB and 1 firewire port cluster on the front. I never really used the front USB but I'm about to sell the computer so I wanted to make sure it was working. When I plug in a mouse to the ports up front, they work no problem. if i plug in something USB 2, like a thumb drive or an iPod, Windows 7 says drivers were not properly installed and the device will not work, not just reduced speed, not working at all. I thought there was no physical difference between USB 1.1 and USB 2 ports? Any idea what is up?
 
I don't have the full details, but I believe that the front USB ports are actually USB 1.1 ports and the motherboard recognizes them as such. Assuming that your Chenming case is over five years old, that's a likely possibility.
 
My guess would be there is something up with the wiring to the front ports that is screwing up it's high-speed performance.

Is the screen on the cable actually earthed?

There is over a factor of 100 difference in datarates between a low speed device and a high speed device...
 
there is no physical difference between a usb 2.0 port and 1.1 port...do the ports go to some type of pcb before connecting to your motherboard?
 
It looks like there is some kind of a PCB underneath the ports. This is a several year old case but it seems like USB 2.0 was standard by then, maybe I should just get a 3.5" card reader with USB on it
