Yes, I know this, but thanks for the reminder. The gma500 driver as I intend to use it looks good enough though. > The usb would best be viewed with a more detailed lsusb (-vv or similar) > but I'd guess that Attached lsusb -vv > Syntek is the camera There are two cameras, one front one rear. > Primax is the built in mouse AFAIK there is no built in mouse, I attach a USB one to get a pointing device. > Option is the 3G Modem Ok. > so the touch screen would presumably be hiding somewhere else.

Alright! Thank you very much for your valuable input and the time taken. I still have the SFR linux iso, maybe reinstalling the working OS could help me. I'll need more room, so buy a micro-SD card to host both systems :) One more question: would you advise me to stick to -rc kernels (more stable?) or move to git (more appropriate?) for a newbee in linux device drivers development?
