I believe option is better in this case. > ========================================================================= > With the patch (the system already has two FT4232 chips, hence ttyUSB8 > as a first port): > ========================================================================= > > # usb 1-1.4: new high-speed USB device number 5 using musb-hdrc > option 1-1.4:1.0: GSM modem (1-port) converter detected > usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB8 > option 1-1.4:1.1: GSM modem (1-port) converter detected > usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB9 > option 1-1.4:1.2: GSM modem (1-port) converter detected > usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB10 > option 1-1.4:1.3: GSM modem (1-port) converter detected > usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB11 > qmi_wwan 1-1.4:1.4: cdc-wdm0: USB WDM device > qmi_wwan 1-1.4:1.4 wwan0: register 'qmi_wwan' at > usb-musb-hdrc.0.auto-1.4, WWAN/QMI device, 9e:04:56:2e:82:be Yes, but that is pure luck. There is nothing in the patch preventing the option driver from binding to interface #4, which would have blocked it from qmi_wwan. The patch should blacklist this interface. > | ports: 'ttyUSB10 (at), ttyUSB11 (at), ttyUSB8 (qcdm), cdc-wdm0 (qmi), wwan0 (net)' Great! Then we know what most of the ports are, and we know that the QMI function is working. Thanks. The "extra" serial port seems to be an additional AT command function. The missing port (ttyUSB9) is most probably NMEA? You might need to write $GPS_START to it.
