I guess now would be a good time to ask for getting those fixes into mainbuild as one of the 6.2 Kernels Changelog entrys was adding support for HP X55 Modem PID in the Driver.

When I first started playing with this modem I started out on Ubuntu. I installed the latest version of the OS. I then built latest kernel, ModemManager, libqmi, libmbim and installed.
