Hp Connectivity Kit on MacOS Catalina

[COB160]

Hello,
I'm trying to connect Hp Prime with Hp Connectivity Kit on my computer, but the program does not detect my calculator at all.

The program is updated and also the calculator firmware! It is not the first time I connect my calculator so it should work.

Any advice? If the problem is Catalina, what I should do to connect the Hp Prime? I have not any Windows computer, and have issues also with virtual machines!

Thank for your help.

I don’t know what kind of mac you have, but I sometimes need to reboot and/or even reset the smc (MacBook 2016, MacBook Air 2019) to make USB operate normally again.

In System Preferences->Security & Privacy->Privacy Tab, make sure that the HP Connectivity Kit.app has permission in the Input Monitoring section.

Also, in System Preferences->Security & Privacy->Privacy Tab, make sure that the HP Connectivity Kit.app has permission to access the Documents Folder in the Files & Folders section.

Good luck!

Macbook Pro early 2015! I tried to reboot and reset the smc. It does not work at all! If I click on apple logo->"about this mac"->"System report..."->"Hardware"->"USB" the calculator does not even appear there!

Thank you, seems to be ok! Do you manage to use Hp Connectivity Kit on Catalina?

Update:

I tried to plug in Hp Prime in another Mac with Sierra and it does not work: same problem the computer does not detect the calculator... Maybe the problem could be the calculator itself?

Are you using the original HP USB cable or a cable that you know 100% for sure is a communication cable and not just a charging cable? They look the same, but the charging cables don't support communication.

If you are not 100% sure of the cable, try connecting to some other (any other) device to verify the cable supports communication, and if successful, try the Prime again.

I have tried several cables... tomorrow I am going to try with windows PC. If it will not work the problem will be the calculator itself. If I reset HP Prime is there a possibility to solve my problem?

Yes. I don't use it often, but when the calculator needs a charge, I use it to re-synch the time.

I started doubting myself, so I just tried it again. My process went like this:

1. Open HP Connection kit on my MacBook Pro (OS 10.15.2)
2. Connect the Prime via the USB cable and a USB-to-USB-C dongle
3. Turn on the Prime
4. After a short wait, less than a minute, the Prime appears in the CK window

I hope this helps...
