this is sys tree i get when i plug in my modem. With this can u say whether my modem is QMI capable? How to add VID/PID pair to the kernel driver and recompile it? Where can i get help? I tried to compile ModemManager and NetworkManager from source a few weeks back, i managed to resolve many dependencies but failed at a particular dependency i don't remember. Please make suggestion on how to proceed. Thanks!
