NTDEV

I built a USB driver with ClassInstall and coInstall dll,
but some error occured when I tried to install the driver,
now I can’t reinstall or uninstall the driver, when I try to uninstall the driver, a messagebox “Windows could not load the installer for theUsb, Contact your hardware vendor for assistance.” but I have copy the class Installer and the coInstaller into the windows system32 folder.
Plz help me uninstall the driver.
