Hello,

I have finally got modem seen and attached to /dev/ttyUSB0
using OpenWrt Barrier Breaker 14.07 and extroot on a TL-MR10U.

A good victory for me :-)

But I cannot connect,
restarting network I have many messages :

I think there is something with USB, sdcard reader and modem are plugged
to a small USB hub.

I have the same message after call of gcom :

root@OpenWrt:/# gcom info -d /dev/ttyUSB0

[ 1584.600000] option1 ttyUSB0: option_instat_callback: error -2

The router  is now powered by it's battery, and serial to computer with ftdi breakout.

I could not find "error -2" with option_instat_callback,
does someone know what is it from ?
Maybe how could I solve it ?

Hello,

I have found this issue https://dev.openwrt.org/ticket/16733

I will try with another USB hub, for now I have the same issue with a fresh received gl.inet

root@GL-iNet:/# ping openwrt.org
PING openwrt.org (78.24.191.177): 56 data bytes
64 bytes from 78.24.191.177: seq=0 ttl=48 time=298.561 ms

I have tried with another hub, it was worst, modem was reseting itself in a loop.

I have made another try on my Debian desktop and the modem connects fine.

I have checked the parameters in network manager, phone number was :

*99#

APN:

free

without username nor password.

I have then edit /etc/chatscripts/3g.chat to change to:

OK      "ATD*99#"

and /etc/config/network to remoce username/password

I have plugged a real power source (not USB from computer ...)

After some:

[   78.930000] option1 ttyUSB0: option_instat_callback: error -2
[   82.020000] option1 ttyUSB0: option_instat_callback: error -2
[   83.100000] option1 ttyUSB0: option_instat_callback: error -2

I can see in ifconfig output:

3g-wan6   Link encap:Point-to-Point Protocol

Houra !!!! \o/
