Usb-1
He might have bought the USB-1 from Uniden, in which case he needs to D/L the driver before installing it.
Would you believe my USB-1 does NOT show up in the device manager? (at least on this WIN XP computer) It does on other computers but not on this one. I can still use it on here, but I have to know what port it is and that is a matter of trying each one that shows up till it works.
