comgt 23:09:44 -> ---->
comgt 23:09:44 -> Error @154, line 4, Could not write to COM device. (1)

issue is serial port settings work around is.
stty -F /dev/ttyUSB0 1:0:8bd:0:3:1c:7f:15:1:5:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0

This is actually with some Huawei Modems on brcm47xx platform with kernel 3.14/3.18;
on ar7xx it works most of the time.

Hi,
I'm having the same problem for some time. I think it was introduced by r43000. Tested only with ar71xx devices (3.10.x and 3.14.x kernels) and some Huawei modems.

root@OpenWrt:~# gcom -d /dev/ttyUSB1 sig
comgt 17:25:45 -> -- Error Report --
comgt 17:25:45 -> ---->                    ^
comgt 17:25:45 -> Error @133, line 8, Could not write to COM device. (1)

root@OpenWrt:~# gcom -d /dev/ttyUSB0 sig
comgt 17:26:32 -> -- Error Report --
comgt 17:26:32 -> ---->                       ^
comgt 17:26:32 -> Error @224, line 13, String is shorter than second argument. (7)

Removing 002-termios.patch apparently solved the problem.
