testing usb ports

Hi,

I believe that my my front usb ports may be faulty.

Is the a free software package that can tell me if the fault lies with the front ports, or the motherboard?

Thanks

Ps. The rear usb ports work well.
I have tried uninstalling and re-installing the drivers.
The motherboard is fairly new.
System is Dell Dimension E520.
OS is Vista Home Premium, 32 bit.

Usually it may be a hardware fault, such as some bad soldiering on some
ports which create a lack of connection from time to time. Check the
front ports out by connecting various different devices with various
different cables.

Also there are 3 different ways that USB connectors are wired.
It could be that the pins on the mainboard are different to the connector
to your case front panel.
I have seen a tester with red and green LEDs that tells you if the port
is wired okay, reversed or no power. I don't know if it tells you about
5 V on the data lines.
