Device bus connectivity

This topic discusses bus connectivity methods for a Windows radial controller device.

A Windows radial controller may use the Microsoft provided inbox drivers to connect to its Windows host using the following:

  • HID over Bluetooth
  • HID over USB
  • HID over I2C

To utilize any other bus other than those listed above, a third-party HID mini-port driver is required. Microsoft strongly recommends using the Microsoft-provided inbox drivers.

We recommend using the Microsoft-provided inbox drivers. For devices that aggregate information from multiple input sources, a third-party HID filter driver may be required. If you elect to use a third-party mini-port or filter driver, the driver should be included in any OEM and system Restore images, and should also be made available through Windows Update.
