Hi, would someone pls help to troubleshoot init of Huawei E1750?

This is what I get in the log (dmesg):

My chan_dongle is set to have ttyUSB1/2, so based on brief description in troubleshooting section, there is something wrong... 

; dongle required settings
[dongle0]
audio=/dev/ttyUSB1              ; tty port for audio connection;        no default value
data=/dev/ttyUSB2               ; tty port for AT commands;             no default value

And subsequently, asterisk doesn't see any dongle:

I'd very much appreciate any help to figure out what's wrong. Thanks
