Table 9-8. CHidTrayDevice Methods
Method Type Description
RequestNewUsageValues() Public This method sets up and issues a Set Feature request to the HID
device, which now simply requests the wireless device to provide
an update of its battery level the next time it communicates with the
USB bridge.
UpdateUsageValues() Public This method retrieves the latest usage values from the USB
bridge, which includes wireless channel, wireless PN code, last
reported battery level, and signal strength.
UpdateDeviceInfo() Public This method makes a call to update the HID device usage values
and displays a warning message (if enabled).
GetUsageIDValue() Public This method extracts the value of the provided Usage ID from the
feature data.
VerifyHidDevice() Public This method is called to verify that the HID device is one that
should be added to the list; right now this is done by making sure
the
usage page reported is WIRELESSUSB_USAGEPAGE and
the
usage reported is either
WIRELESSUSB_USAGE_KEYBOARD or
WIRELESSUSB_USAGE_MOUSE.
