no, it didn't... (but it had always been working, before putting the linux driver to the test) >> 3) turned the lapop off and unplugged the power cable.

I agree with you, if I got the same issues both in Windows and in linux, it'd be an hardware problem. But since working and non-working situations are very reproducible, I suppose it is not an hardware problem. In particoular, the camera works in linux on the both conditions (both necessary): having worked in windows and the laptop having been rebooted from windows. And for working in windows, a "deep" boot is necessary (ie a boot from a completely "shut down" situation). Sorry for the terms used, but I don't know how to express better the two different kinds of booting. Hope them were understandable. Well, thank you all for reading and for any suggestion you will write.
