Sample USB Device Drivers

This section describes a template USB device driver that uses the USBA 2.0 framework for the Oracle Solaris environment. This driver demonstrates many of the features discussed in this chapter. This template or skeleton driver is named usbskel.

The usbskel driver is a template that you can use to start your own USB device driver. The usbskel driver demonstrates the following features:
