Dear Cyrille

It is a pleasure to have you here in the forum attending posts.

After some time playing with the emulators, I just received the real HP Prime. I connected it to my Linux computer and I can see it in a terminal with lsusb:

Code:

$ lsusb

Bus 001 Device 012: ID 03f0:2441 Hewlett-Packard

However, I was looking for an option in the Virtual Calculator menu to connect and I didn't see anything. Maybe I miss something... The 'About' dialog box says I am using Build: 2.1.14288 (2019 10 22)

I also tried to send a matrix from the Matrix menu in the real HP Prime. The 'Send' option is active and the calculator tries to send it to the computer. But, on the other side, the Virtual Calculator has no 'Send' option active in its Matrix menu.

Just in case, I checked the logs to find any problem during the connection of the HP Prime and they looked fine (the plug&play system trying to do something with the new device, but nothing serious I believe, no red warnings):

Code:

$ journalctl -f

Thank you for your dedication to this forum!

PS. I enclose a picture to show the appearance of the Virtual Calculator in my Ubuntu 18.04 Linux:

I have not looked at the code recently, but I think that we did, at one point, implement the USB function for Linux in the emulator...

This means that, if the code is still there and linked, you might be able to communicate between the linux emulator and a real calcualtor. This will allow you to send files from your calc to the linux PC through the emulator...

Give it a try and tell me if it works or not...
