I was asking about something more practical ... how do I know that the device is connected? Does it make sense to do it, when obviously it is already detected by the kernel?

I think you should first go through LDD book, then try running some sample programs given in the book. Also go through pdf *lkml*. Both LDD and lkml are available on net. After this try to get understanding of the ALSA or OSS.May be try writing your own driver which will play MP3 on you PC console speaker.-Manish ROn Thu, Aug 20, 2009 at 4:29 PM, Radu <radu@xxxxxxxxxxxx> wrote:
Hi,
I am trying for some time to write some kernel code, but as we all know that's not that easy. I want to write a driver for a no-name mp3 player, just for academic purposes, but I am not sure how should I tackle the problem - will it be a char driver ? how can I detect when it's plugged in/do I need to do that?. Where do I start? How do I do it? Is there any place where I can read about something similar? I've been reading quite a lot lately, but probably not enough.
Thanks a lot for any hints,
Radu.
