Writing Linux USB device drivers is not a difficult task as the usb-skeleton driver shows. This driver, combined with the other current USB drivers, should provide enough examples to help a beginning author create a working driver in a minimal amount of time. The linux-usb-devel mailing list archives also contain a lot of helpful information.I'm trying to write a character device driver in linux. Unfortunately it's not working for any numbers greater than 255. I want this driver specifically to work with value of type long. Anytime I input a value greater than 255, the numbers wrong. 256 goes to 0 etc. I've written a simple character device driver that shows the problem, there might be a lot of unused include statements as I.The following Makefile invokes the kernel’s build system from the kernel source, and the kernel’s Makefile will, in turn, invoke our first driver’s Makefile to build our first driver. To build a Linux driver, you need to have the kernel source (or, at least, the kernel headers) installed on your system.
