Some good tutorials on how to write Linux device drivers (some are old but good for concept-building nonetheless):
- Device Drivers @tldp.org
- Write a Linux Hardware Device Driver
- Introduction to Linux Device Drivers
- Writing a Linux Kernel Driver for an Unknown USB Device
- Writing a Linux device driver module for kernels 3.0 or 2.6 with udev
- Linux Kernel Driver Tutorial
- How to Write a Linux USB Device Driver
- Linux Loadable Kernel Module HOWTO
- Linux Device Drivers, 3rd Edition (PDF)
- Writing device drivers in Linux: A brief tutorial
- A Simple Block Driver for Linux Kernel 2.6.31
- Enhanced char driver
- The Linux Kernel Module Programming Guide
- Free Electrons Docs
- LFY Linux Device Driver Series
- Write your first Linux kernel module
The Free Electrons LXR (Linux Cross Reference) for referring the kernel source. However, I prefer ctags and cscope for lengthy source-code browsing sessions.

Welcome!
Hi, do you have any resources for writing a usb webcam driver? I have never written a driver before. Thanks.
This should fix you 😉 –

Thanks for the quick reply. Unfortunately my webcam does not work this that driver. I have a Creative Live Cam HD which has an on-board H.264 encoder. However, v4l2-ctl only shows getting an incoming feed of MJPEG so I’m trying to find a driver to support my webcam or I have to write my own.
No problem! Check in the opensource webcam driver developer forums or mail an author directly. They should be able to guide you.
