To communicate with USB IO Driver one must first enumerate the device. The enumeration of the device returns a device name. This device name is used to open the interface, using CreateFile(). Once you have the handle from CreateFile() you can use DeviceIOControl() to communicate to the USB IO Device and CloseHandle() to close it. the USB subsystem and its API for USB device drivers. The first section will deal with the basics of USB devices. You will learn about different types of devices and their properties. Going into detail you will see how USB devices communicate on the bus. The second section gives an overview of the Linux USB subsystem [2] and the device driver.  · retval = usb_register(led_driver); if (retval) err("usb_register failed. " "Error number %d", retval); Likewise, when the driver is unloaded from the system, it must unregister itself from the USB core: usb_deregister(led_driver); The led_probe() function is called when the USB core has found our USB lamp device.

There are various resources and tutorials on the internet for writing device drivers, however, they are somewhat scarce as compared to writing a “hello world” GUI program for Windows. retval = usb_register(led_driver); if (retval) err("usb_register failed.
