You can only uninstall drivers
if there's an option to uninstall them. They are generally located in one of 3 places:
- the Start Menu
- the Control Panel...Programs...Uninstall a program applet
- the Device Manager Right click on Device and select "Uninstall". If there's a box to check that says "Delete the driver
software for this device" then you can remove it that way.
Uninstalling drivers is done at your own risk. Backup your stuff, set system restore points, and rename rather than delete (if possible). But, even so, if you delete the wrong driver - you may not get back into that copy of Windows again. The good news is that if you have a backup copy of the deleted driver you can usually replace it from outside of Windows - and that will usually fix the problem.

Click on the little floppy disk icon - not on the Free driver scan
If that doesn't work, then I'd have to recommend not using the device any longer (or, at least while we're troubleshooting). I suspect that no one is supporting Windows 7 for this device. We can attempt to force installation of Vista drivers - but that doesn't always work out very well.
