How can I check that tmff2 is installed correctly?

Hello, I would just like to know if it is necessary to reinstall hid-tmff2 when upgrading the Linux kernel.

Hello, if you installed the driver with the manual method in the README then you'll have to reinstall the driver every time you upgrade the kernel. If you used the DKMS method or installed via a package manager, then the driver should automatically be reinstalled and you shouldn't have to do anything.

How can I check that tmff2 is installed correctly?

You can try running sudo modprobe hid-tmff-new. If it doesn't say anything, the driver is installed, otherwise it prints an error.

ok :)
I have changed the kernel several times since installation, and when I type the line you gave me, I don't get any errors. I assume that it is therefore installed correctly.
Thank you and have a nice day.
