This is the result of AT+QCFG=? on our modem: AT+QCFG=? +QCFG: "usbcfg",<vid>,<pid>,<diag>,<nmea>,<at_port>,<modem>,<rmnet>,<adb>,<uac> AT+QCFG="usbcfg"? +QCFG: "usbcfg",0x2C7C,0x0121,1,1,1,1,1,1,0 Unfortunately AT+QLINUXCMD is not available in this firmware revision (EC21EFAR06A02M4G). Although the Linux lsusb shows interface #5 with an ADB interface activated, the latest revision of adb in Linux does not pick up the interface. I tried putting the vendor ID in ~/.android/adb_usb.ini and checked udev permissions, but no avail. Meanwhile I could get the ADB shell in Windows. Does someone have any ideas why it is not working in Linux?
