Does it make any difference if you unplug that webcam, or > > plug it into the other high-speed bus? > Can't do so, its built-in. But I can plug printer into another usb bus, I found a single port (this notebook has 4 ports) that is on bus #1, problem is that it it on the other side of the notebook, and from the point where the printer stands the cable isn't long enough to reach it. I do some more testing soon, buy another and longer cable Anyway couldn't crash the printer even once with 'good' driver. In other words I was sure I found a cause for this problem, but it seems I found nothing or maybe a bad cable (I did some tests in windows - but as things unroll, this printer can work quite reliably sometimes that is) So again big thanks, Best regards, Maxim Levitsky -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
