After many trials, I observe that the image quality is recovered when no other USB2.0 devices are connected to the GA-MA78GM mother board (WIFI dongle or Hard Drive). This problems seems to be releated to this bug http://bugzilla.kernel.org/show_bug.cgi?id=11599 and/or that one https://bugs.launchpad.net/ubuntu/+source/linux/+bug/256492. But it seems that the ehcd-hci bug is solved (but not for me!) Any idea?
