<br></blockquote></div><br><br>Hello Ashok,<br><br>A few days ago I wrote a lengthy answer to the same question in quora, if you want to take a look: <a href="http://www.quora.com/Linux/Whats-the-best-way-to-learn-device-driver-development-on-Linux">www.quora.com/Linux/Whats-the-best-way-to-learn-device-driver-development-on-Linux</a><br>

<br>Short answer: <br><br>If you have an Android device, there is a big probability that the drivers for that hardware have not yet been pushed upstream. Android and Linux differ slightly but enough to force a developer to choose to write a driver either for Android or Linux.<br>

<br>So, a useful contribution and an excellent learning process could be porting Android device drivers to Linux.<br clear="all"><br>-- <br>Javier Martínez Canillas<br>(+34) 682 39 81 69<br>Barcelona, Spain<br>
