9.2.3.5CHidTrayDevice Class Methods

The CHidTrayDevice class is derived from the CHidDevice class and is the class used to interface with WirelessUSB devices.

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.

9.2.3.6CHidTrayManager Class Methods

The CHidTrayManager class is derived from the CHidManager class and is used to manage Wire- lessUSB devices.

Table 9-9. CHidTrayManager Methods

Method	Type	Description
NewHidDevice()	Protected	This method creates a new HID device, initializes it, and adds it to the
		list of existing HID devices.
DeleteHidDevice()	Protected	This method removes the HID device from the list and deletes the
		HID device.

9.3Development Environment

The following tools are required to build and develop the Wireless USB Software application.

■Microsoft Visual C++ .NET

■Windows Driver Development Kit (DDK)

A Microsoft Windows based PC is used for tool execution.

The Microsoft Visual C++ .NET solution file can be found at the following location:
