A USB Class Driver sample demonstrating the implementation of a USB Class Driver for a HID Class device - specifically the MacAlly TenKey keypad device.
Description
This code demonstrates how to support a HID device via the driverInitialize entry point. It also demonstrates the use of the USBFindNextInterface and the USBOpenDevice calls for device configuration and setup.
Building the Code
This sample was built using the Metrowerks CodeWarrior Pro 2, IDE v2.1 environment and the Mac OS USB DDK v1.0.1. Also required, is the Universal Interfaces and Libraries 3.1.
To rebuild the project, first place the USBKeypad folder into the USBDDK:Examples: folder. The project file assumes specific access paths that are project specific. The resulting class driver, USBHIDMacAllyTenKey, is built into the USBDDK:Extensions-MCWBuilt: folder.
You can also build this sample using MPW which has already been configured for the USB DDK. The USBKeypad sample will appear as another sample in the USBDDK menu.
Using the Code
Place the class driver, USBHIDMacAllyTenKey, into the Extension folder, then plug in the Mac Ally TenKey device.
