Huawei e367 on 18.06.2

Installing and Using OpenWrt

I'm trying to get a Huawei e367 USB modem working on a zyxel router following the page How To use LTE modem in QMI mode for WAN connection. Permissions seem to be wrong according to the page they should be

ls -l /dev/cdc-wdm0
crw-r--r--    1 root     root      180, 176 Oct  1 12:03 /dev/cdc-wdm0

but they are as below

 root@OpenWrt:~# ls -l /dev/cdc-wdm0
crw-------    1 root     root      180, 176 Apr 25 13:48 /dev/cdc-wdm0

cat /sys/kernel/debug/usb/devices
produces

Am I going about this correctly for this modem? Is this a modeswitch problem?
Thanks in advance

Everything looks fine. The permission should not be a problem as everything runs as root anyway.

Mode switching has already been successful. You can see that the qmi_wwan driver has bound to the expected USB interfaces. You might want to install kmod-usb-serial-option as well to get /det/ttyUSBx devices for the serial functions currently having "Driver=(none)", but this is entirely optional. What you already have should be enough for a "qmi" or "wwan" protocol interface. See

UMTS/GPRS/EV_DO seems to work but not qmi. Any suggestions welcome.

What do you mean by that?

If the selected protocol for the interface is UTMS etc the status page shows the modem data in the ipv4 box (ip DNS address etc). If the protocol is QMI mobile the interface is not available and the status page reflects that.
