If all you're looking for is the extended signal query, the MBIM driver does support this if the modem implements the ATDS (AT&T Device Services) UUID. What do you get for: mbimcli -p -d /dev/cdc-wdm<whatever> --atds-query-signal Dan > Next, I set the USB composition to AT+KUSBCOMP=0 which enumerates 4x > CDC-NCM + 3x CDC-ACM.
