USB Combination Devices - Demonstarted by a Combination Mouse and Gamepad Device
This Technical Brief describes a USB combination device consisting of a mouse and a gamepad implemented on a PIC16C765. Previous technical briefs
describe the translation of a PS/2 â mouse to a USB mouse (TB055) and the translation of a gameport gamepad to a USB gamepad (TB054). These two
devices were combined to form the USB combination device described in this brief. Details about the translation and implementation of the mouse and the gamepad are not covered. Refer to the earlier briefs for this information as well as their circuit diagrams. This brief focuses on setting up the descriptors appropriately for a combination device.
