Unknown Device in Device Manager for USB device in WinXP
Posted on 2003-02-26
I have a USB device for which I have the proper driver. When I install the device, WinXP immediately recognizes the device as "New Hardware, USB Device", and then "Unknown Device". Device manager shows it as a USB Unknown Device. Device properties shows that there is no driver installed when Driver details is clicked. I have tried uninstalling the device and re-installing, bet I haven't been able to get any other result. I have the valid device driver from the manufacturer, but clicking "Have Disk" doesn't allow me to load the correct driver either.
Is there some way to "purge" all reference to the device in the registry and start over?
I've tried to word my question in a generic way, since I've had this problem with 2 different devices. It seems to occur if the device hardware is initially installed without the driver, and you later try to install the correct driver.
