Asmedia Extensible Host Controller Driver

I installed the latest ASMedia USB 3 driver for XP. It doesn't work. The driver also screws up my USB 2 ports. So I need to uninstall it.
The uninstall directions are useless, they are:
Use the following procedure to uninstall the software:
1. Select 'Uninstall' from the following steps:
- Go to 'Start'
- Select 'Control Panel'
- Select 'Add or Remove Programs'
- Find 'Asmedia ASM104x USB3.0 Host Controller Driver',
select it and click the 'Remove' button.
you can also use the following procedure to unisntall the
software:
- Go to 'Start'
- Select 'Program'
- Select 'Asmedia Technology'
- Select 'ASM104x USB3.0 Driver'
- Click shortcut 'uninstall'
Becasue there is no option to 'remove program' or 'uninstall' as described. They also have a warning in the readme.txt file:
9. UNINSTALLATION NON-DRIVER COMPONENTS
Removal of this software from the system will render any
USB devices inaccessible by the operating system;
therefore, uninstallation procedure will only uninstall
non-critical components of this software (user interface,
start menu links, etc.).
So I need to uninstall the driver manually in a way that won't screw anything else up.
Thanks
