Huawei me909s-120 mPCIe vs Huawei E3372h USB (LTE modems)
I have a 3372h which works fine, but I have to manually activate it after reboot (plug off/plug in/usbmodswitch/activate interface + edit /etc/inc/util.inc file in order not to hang in boot)). If I replace it with something like me909s-120, which is a mPCIe card, will I avoid that and keep things more automated?
I believe that should work though I have not tested it myself.
Although those are mPCIe form-factor they are still USB connected. It is far more difficult to remove it accidentally though and I would not expect it to require mode-switching.
It may even be possible to use the cellular package with that to get link stats.
