I check the AT configuration of the module, and even tried all the USB channel maps that include MBIM support (e.g. AT!USBCOMP=?), rebooting in between, but never showed up as LTE interface. I didn't adjust any of the USB identifier things - left those the defaults. Enabled "raw" and "debug" topics, but I never saw anything related to the MBIM and/or LTE interface. The same USB miniPCIe adapter with the MC7354 modem worked under Windows 10 before and after in MBIM mode, so pretty sure the module etc works.
I can provide the configuration (it's the MT default, HomeAP, I guess?) and/or supout.rifs if needed. But curious if MBIM mode should be working in beta1 on the hAP ac^2? ...am I wasting my time trying now...or perhaps there are some USB things I can set on the MC7354 modem to cause it to picked up....
Background: "MBIM support " == modems here https://wiki.mikrotik.com/wiki/Manual:P ... lar_modems that say v7.xx (LTE). Mikrotik's LTE interfaces in v6 only use ECM mode modems, v7 promised to add MBIM mode modems. MBIM is supported by Windows etc and has wide support in modem modules. While PPP mode totally works, it has a limit of ~30Mb/s since the interface between the router and module is a serial line.
