After 12 disconnect messages sometime I see a reset message, like the = shown in this trace, and the touch is not working. Sometime this reset it's= not send and the touchs works ok. My guess is that the Xorg sometime runs = and get access to touch before this 4 or 5 second watchdog is executed and then the touch is not disconnected = this last time...

Anybody has some experience in this kind of USB errors? Is it a known = behavior modified in a more recent kernel?

Any hint is welcome
