My Front Panel USB Port is not working but the rear panel is in good condition.
Could any one aid me to determine the solution for this.

Thanks....

Brief summary and a focused troubleshooting path that goes deeper than just “check the header” or Device Manager (those were already suggested by @ryan461 and and confirmed they were tried).

Start with safe, hardware-level isolation: power off and unplug the PC, open the case and inspect the front-panel USB cable and its plastic connector for broken wires, bent pins or corrosion. With power still off do a continuity check from the front USB port shield/pins back to the case connector to make sure wiring isn’t open. If you have a spare internal USB header, temporarily plug the front-panel cable into it — if the front ports then work the motherboard header is the problem; if they still don’t work the front-panel wiring or the small PCB behind the ports is faulty.

If wiring looks intact, measure voltages: power the system on and carefully measure ~+5V between VBUS and ground at the internal USB header (use caution and avoid shorting pins). Expect about 5V; if VBUS is missing at the header but present at rear ports, the board’s USB supply or a board-mounted resettable fuse/trace is likely damaged. Visual signs (burn marks, blown components) near the header are telling. Replacing board fuses or traces is an advanced repair — consider warranty/repair service before attempting.

Software and quick-workaround options: update/reinstall chipset and USB host-controller drivers from the motherboard maker, and test from a Linux live USB to rule out OS driver problems. As a practical workaround, use a powered USB hub or a simple rear-to-front USB bracket if you need front access immediately.

If the front-panel module is at fault it’s inexpensive to replace the case front I/O or fit a 3.5" bay adapter. If you need step-by-step voltmeter guidance or part-identification help, post the motherboard model and the front-panel cable picture so the next reply can be precise.

Re: Front Panel USB Port is not working but the rear panel

please provide more information on what you're using. Im thinking desktop so check the connection from the case to the USB header on the mobo.

Yes i am using desktop & i have checked my mobo USB1 & USB2 but i am not able to prove whether its in a good /working condition or not....
so is there any other way to check what s gone wrong in it
Also i need to know are they both different connection (Rear & front pannel)??
if so then i can conclude that my front pannel wont work any more because mobo is not passing the power to the front pannel..

Some things I would check:

Look in the Windows Device manager. Do the USBs show up here? Any yellow warnings?

Look in Bios. Is there an option to disable the Front USBs?
