It's like the data lanes on the USB connection are severed, but across multiple cables, which doesn't make sense unless the USB connection on the calc is damaged but still accepts power?

Unfortunately, this is possible because the power pins and data transmission pins are different. If the socket was accidentally bent too hard, one of the data pins may have disconnected, but charging would still work. However, it's worth trying what matalog suggests first. If that doesn't help, disassemble the HP Prime and inspect these pins as shown in the picture to see if there is any slight looseness in any of the middle pins. Perhaps a light soldering might be enough.
