Please help! USB device not recognized??

[humdog]

I bought a logitech headphones with mic and when I plug it into the usb port
it says that it can not find the software???  It did not come with software....

Then when i plugged another usb device into a usb port (griffin imic) my
computer told me the same thing.  Which tells me it's not the hardware but
instead some problem with my computer not recogizing and installing the
headphones and imic properly onto my computer???

I'm not a tech head so if anyone could help me out i would really appreciate
it.  I can't record anything until i get this sorted out.

Thanks,

Peter
ps. I am using windows xp and have all the updates and
service pak 2 as well!

Go to Control Panel / System / Hardware / Device Manager...right click ALL instances of USB ports/hubs and select remove.
Reboot with all USB devices removed
Then power down and introduce one USB device at a time and restart.
