New & old USB-2416 & AI-EXP32 Not recognized



We have an installation that previously detected and worked with a USB-2416 & AI-EXP32 combination. It has stopped communicating with the PC. The USB port was verified operational with a flash drive. Using both a new spare USB-2416 & AI-EXP32 combination on the same PC were also not detected by Instacal. Can you provide trouble shooting suggestions for this PC? Changing PCs is more difficult.

you need not 'change' to another PC, but I would definitely use a another PC just as a test.

Trouble shooting suggestions:

  • run windows update
  • run a virus scan
  • un-install all MCC software, delete any remaining files and folders.
  • use an earlier windows restore point.
  • Confirm the USB-2416 use by itself works.
  • remove any USB cable extenders
  • be sure the USB-2416 is plugged in DIRECTLY to the computer using a USB cable no longer than 3 meters. -do NOT use any external hubs or cable extenders, nor USB ports on a computer's monitor nor docking stations.

Failing that, it would helpful to know:

What version of Windows?

What version of InstaCal?

How does the USB-2416 show up in the device manager?
