Linux and HP Prime

[gfbci]

The advances I have made so far have been the result of trial and error but I risk some recommendations, even without knowing exactly what the mechanisms involved are.
Make sure the package libhidapi-hidraw0 has been installed and that the physical Prime is being identified correctly by the Linux kernel.
My output of the command "lsusb -v" include:

Start CK before connecting the calculator. Sometimes it is necessary to start manually the command "wineserver" before the CK.
Always start all commands from a terminal, error messages can help a lot, as well as system logs.
My CK can handle the physical Prime, native Linux emulator and window (wine) emulator, all at the same time!
Unfortunately I can’t browse the content of the physical Prime. The terminal shows the error when I try:
===
"0041:err:hid_report:process_hid_report Device reports coming in too fast, last report not read yet!"
===
The backup context-sensitive menu is not available either...
Even so, I have no difficulties in transferring content or taking screenshots.

Good luck and stay safe!
