• This also happen when I do "Activate USB disk" before plugging the cable in.
• If I put it in while on the "About" screen after reset, it doesn't throw an error directly, but after dismissing the screen get stuck on "Checking QSPI contents …"
• I manage, sometimes, to make USB work with this procedure:
  1. Press the reset button and wait for the "About" screen to appear
  2. Prepare the USB cable close to the plug
  3. Dismiss the about screen by pressing "Exit" and quickly insert the USB cable
  4. Some other messages I got while trying to make it work:

I just connected my DM42 running f/w Ver 3.71 to my PC via USB cable with no trouble; it worked as expected, files on Flash were visisble to the PC, etc. so the issue reported above is not present in all 3.7 f/w DM42 machines. I don't doubt that the 2 reports are real problems, I just wanted to verify and confirm that this problem is *NOT* present in all machines.
