DM-41X USB Disk Missing

[trojdor]

CDMACKAY is certainly correct about this.

I had to modify a USB cable by filing off a substantial amount of plastic/rubber material (at the calculator end) to allow it to fit and work properly. It's now dedicated for the SM calculators I own.

Otherwise, like GERRYS, the cable wouldn't work consistently...and it would appear as if there was a hardware problem with the calculator.

If you use a good light and look very closely, it's easy to see/fix the problem.
