Ricardo Rodriguez Salinas Posted October 9, 2018 Posted October 9, 2018 (edited) Hi team, I want to install a 3G USB modem from Huawei exactly the e173 one in a Nexbox A95X 1/8 TVBOX, I can see the modem is on modem mode in lsusb, but I cant get work that modem. I can't see the serial ports that supposed to be in /dev/ directory, can you help me? Edited October 9, 2018 by Ricardo Rodriguez Salinas
balbes150 Posted October 10, 2018 Posted October 10, 2018 The version of the image and the kernel you're trying, should we guess for ourselves ?
Ricardo Rodriguez Salinas Posted October 12, 2018 Author Posted October 12, 2018 thanks for your quick response, sorry I'm new here I don't know how to write down in this kind of topics I got installed this one ARMBIAN 5.60 user-built Ubuntu 18.04.1 LTS 4.18.7-aml-s9xxx The modem is detected but I can't see the serial ports root@A95X:~# lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 12d1:1c05 Huawei Technologies Co., Ltd. Broadband stick (modem on) Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@A95X:~# ls -la /dev/ttyUSB* ls: cannot access '/dev/ttyUSB*': No such file or directory thanks

Check what "dmesg" is reporting, could be that specific driver is not present in this kernel ...
Ricardo Rodriguez Salinas Posted October 12, 2018 Author Posted October 12, 2018 With or without the modem inserted, shows me the same tty* files
martinayotte Posted October 12, 2018 Posted October 12, 2018 According to "dmesg" output, no driver is associated with USB insertion ... Check the possibility of presence/absence of those kernel configs : grep USB_SERIAL_OPTION /boot/config-* grep USB_NET_QMI_WWAN /boot/config-* grep CONFIG_USB_NET_HUAWEI_CDC_NCM /boot/config-*
John Minaa Posted March 11, 2019 Posted March 11, 2019 I am also facing an issue in my 3G modem serial ports, I think it is COM Port Selection related issue. Error is "Device connected, Serial open failed". Can anyone guide me, that how can I resolve this issue.?
