more information on the installed driver, refer to the steps below.

• In order to verify this, navigate to Device Manager → Human Interface Devices → I2C HID Device. Right click
on the Detail tab and choose Hardware IDs.

• If the device is not recognized, check if it is displayed under Unknown Devices and update the driver for the
unknown device.
