To get rid of the legacy cruft, newer ways to present USB-connected LTE modems like QMI and MBIM have been developed. My issue is that QMI_WWAN driver does not detect my BG95 module when I power it on. The management application is responsible for negotiating a control message size complying with the requirements in section 9. Sometimes this is not enough, though, as devices with NCM and MBIM layouts are both generic, and the kernel may choose the NCM over the MBIM one by default, while the MBIM one is really preferred in general. fix: 1. Many carriers Both MBIM and QMI use existing Ethernet over USB standards with an added control channel. There are no obvious gaps in this topic, but there may still be some posts missing at the end. This recipe explains how to setup An ongoing debate is taking place between modem users as to which protocol is better.
