I would say that is the most probably cause for the issue.

You may try this:

Make sure the Windows can detect the USB device (the calculator, that is).
When the calculator is plugged to the PC:
- You should hear the typical Windows sound of a USB device being recognized.
- Open Windows Device Manager, select "Human Interfaces Devices" and you should have two additional entries: "HID-Compliant Device" and "USB Input Device". These two entries are removed as soon as you unplug the calculator from the USB PC port.

Uninstall the HP Connectivity software from Windows Control Panel.
Reboot the PC.
Do a fresh install of the HP Connectivity software.

It is well known that not all Windows PC are created equal.
Try a different USB port and a different PC.
The USB port must have power, so do not use hubs, etc in between the PC and the calculator.
The USB should be version 2 (I never tried old USB 1.1 and the new v3 may cause issues as well).
