ANTUSB-m and ANTUSB2 drivers:
The ANTUSB-m and ANTUSB2 Stick drivers can be uninstalled via Windows’ Device Manager, then reinstalled by simply re-inserting the USB device and allowing windows update to download the drivers. Alternatively, the drivers could be downloaded from the website here and installed manually.
ANTUSB1 drivers:
Re-installing the ANTUSB1 drivers is not always a trivial procedure. To do this properly, the old ANTUSB1 driver must first be completely removed from the system. Unfortunately, this is not as easy as uninstalling the driver via Device Manager. To completely remove the ANTUSB1 driver in Windows XP, please follow the technical note “Uninstalling USB1 Drivers” . Once the old drivers are completely removed, the new drivers may be installed using the standard procedure.
