Disabling Specific USB Drivers
You can disable specific types of USB devices by disabling their client driver. For example, USB printers can be disabled by disabling the usbprn driver that directs them. Disabling usbprn does not affect other kinds of devices, such as USB storage devices.
The following table identifies some USB device types and their corresponding drivers.
