How to reset USB port memory?

After connecting a USB phone handset, Vista loaded the driver then
requested a reboot. I then realised that only the USB microphone device
showed up in Control panel/Sound/Recording menu. The USB speaker device
didn't register.

I plugged the handset in an other USB port. Driver loaded, did the
requiered reboot and this time both microphone and speaker are listed in
as USB sound device.

If I return the uSB hanseet to the first USB port, it has memorise the
driver setting and it still recognize only the microphone. How can I rest
the "driver memory" for this USB port. I imagine it's somewhere in the
registry but where ?

Thanks in advance

Plug another, different type of device (USB memory stick, etc.) into the
original USB port?

Thanks Cal Bear, I did think of it. I plugged a mouse ... mouse driver
loaded, mouse worked but handset is still remembered as having only a
microphone...
Too bad didn't work :-(

Go to Device Manager, find the offending port and delete the driver, reboot
and you should have the USB driver installed, then plug in your device. If
you are going thru a hub, that may be your problem.
