Front USB not working

[attman]

I have a number of older PCs that have 2 USBs on motherboard on rear and 2 on the front (connected via wire).

The rear USBs see and allow usb disks to attach, the front do not.

Anyone any ideas why this would be?

Thanks

are they in the right place on the motherboard?

I have never managed to get the front USB ports working in my current case on my last three MBs. It can only be the connections but hell if I can see whats wrong.

When plugging devices in windows trries to configure but it fails so the cables must be correctly connected dont you think?

Are the mobo & case same USB revision, e.g. USB 2.0? Had a USB 2.0 mobo & older case & latter's USB header would not fit/work (vice versa).

Is it possible to test if the speed you're getting on your USB ports up to scratch or functioning properly?
