Hi Amol, the corresponding kernel patch has been submitted here by another EM919x user: https://lore.kernel.org/linux-usb/[email protected]/ Unless Sierra Wireless has changed their mind recently EM919x may not support QMI mode, see https://forum.sierrawireless.com/t/em9190-usbcomp-settings/22497/6 . W.r.t. the DEVICE_CAPS mentioned here https://lists.freedesktop.org/archives/libmbim-devel/2020-August/001108.html the (custom) data class value reported has now changed to Data Class: 0x8000003c, UMTS, HSDPA, HSUPA, LTE, Custom .... .... .... .... .... .... .... ...0 = GPRS: Not supported .... .... .... .... .... .... .... ..0. = EDGE: Not supported .... .... .... .... .... .... .... .1.. = UMTS: Supported .... .... .... .... .... .... .... 1... = HSDPA: Supported .... .... .... .... .... .... ...1 .... = HSUPA: Supported .... .... .... .... .... .... ..1. .... = LTE: Supported .... .... .... .... 0000 0000 00.. .... = Reserved for future GSM classes: Not supported .... .... .... ...0 .... .... .... .... = 1xRTT: Not supported .... .... .... ..0. .... .... .... .... = 1xEV-DO: Not supported .... .... .... .0.. .... .... .... .... = 1xEV-DO RevA: Not supported .... .... .... 0... .... .... .... .... = 1xEVDV: Not supported .... .... ...0 .... .... .... .... .... = 3xRTT: Not supported .... .... ..0. .... .... .... .... .... = 1xEV-DO RevB: Not supported .... .... .0.. .... .... .... .... .... = UMB: Not supported .000 0000 0... .... .... .... .... .... = Reserved for future CDMA classes: Not supported 1... .... .... .... .... .... .... .... = Custom: Supported and Custom Data Class: 5G on a Thales MV31-W running a recent firmware. For a more comprehensive 5G support libmbim/ModemManager would probably have to implement Microsoft's 5G MBIM extensions mentioned by Bjørn or rely on QMI-over-MBIM tunneling. HTH to get you started while waiting for the device to arrive...
