[maemo-developers] Maemo at Google's Summer of Code 2007?

[From: Edgard Lima]

see previous mail...the kernel source code for gadgets are available

to tell you the truth I'm already writing such gadget (and I hope finish 
it soon). If you want we could exchange some ideas.

to write in user-space...hum...I don't know if it could be possible with 
"gadgetfs" (I have to study more and ask the gadget guys)....But I'm 
sure the best way is to write a UVC gadget.

To do all this you don't have to look into v4l2 driver, you have just to 
learn how to write a simple v4l2 app. I mean open /dev/video0 and talk 
v4l2 API and translate it to UVC.
