How can I remove the device drivers for a USB device that isn't plugged in?
When it's not plugged in, it doesn't show up in the hardware list. And I
don't have the unit anymore, so I can't plug it in.
Thanks.
1. Open command prompt window
2. type "set devmgr_show_nonpresent_devices=1" without the quotes
<enter>
3. type "cd x:\windows\system32" where "x" is the drive you have xp
loaded on <enter>
4. type "start devmgmt.msc" <enter>
5. select "view hidden devices" when hardware list comes up
6. Find your device and remove it.
7. Quit device manager and close command prompt
Just selecting "view hidden devices" from the regular device manager
window will not show devices that are not currently installed. You
have to tell windows to show all devices that have ever been installed
on your machine by using the above command prompt procedure.
