Creative E-Mu 0202 USB driver writing

[gogitosbanditos]

I have the usb sound card above. And I don't want to use Windows.
So i decided to write my own driver.
What to start with?
Can you advice some books (in pdf) or articles that can help?
Can I transform Mac driver I already have to Linux one? I also have a driver for WinXP, but OSX is BSD-based system, with closed code, but OSX has similar architecture to Linux.
I have Ubuntu 8.10 Intrepid.

Thanx in advance.

Great idea. I think it belongs in the developers section of this board though...

Hi!

What kind of articles are you looking for? Alsa driver programming? Why don't you have a look at the existing (alsa-usb) drivers?

Hi, you should check this: http://www.alsa-project.org/main/index. ... ative_Labs ...just scroll down to see the E-MU 0202 USB and click "details"

There is a informative article on writing Linux device drivers at the Free Software Magazine link below, but it is not working at the moment as FSF seems to be down.

Also, the link below is about writing UDev rules, which I had to do for my sound card at some point.

Not sure how much of these you need to know, depends on how well your device is detected and proprietary from USB Audio standard.

Happy diggin!

It seems that 0202 should really work on linux:
