Hello,
Have you found a solution because I have the same problem on dozens of machines from the same joblot . That's almost half of my machines that have problems. What I noticed on certain machines is that the USB port works for a few moments when the PC starts up, then it deactivates. I don't think it's a physical port problem because it repeats itself on several machines. I have never encountered this problem on the M710q
Thx...
