However, sometimes the name of the chipset is left in the firmware revision: you can try looking if there's any hint in the output of the device caps request. If it's a Qualcomm modem it should probably also support QMI-over-MBIM service, so maybe you can also try a few DMS requests (--dms-get-software-version, --dms-get-revision...). Sometimes also the USB descriptors can be useful. Regards, Daniele > Best regards, > Seunghun
