HP Prime Connectivity only works with supplied HP Prime USB Cable

Hi,

I'm experiencing some odd behavior and wanted to post to the group. I've discovered that although my Prime calculator will charge just fine with any old USB <-> microUSB cable, the HP Prime and Prime Connectivity Kit will only see my Prime Calculator if I use the original cable supplied by HP with the calculator. This seems strange to me because I've seen several posts online that say that you can use any cable with your Prime calculator. That's true for charging but does not seem to be true for using the HP Connectivity Kit for sharing and updating. Knowing this I'd love to get a spare cable now. I've found the part number but cannot find a supplier of the cable.
