Problem with olinuxino wifi, android and USB 3G dongle

[tommi]

Hi,

does anyone have any experience using USB 3G dongle in android preinstalled with board. I have tried two different sticks with bit different results.

With Huawei 353s-2 (ports changed not to have CD/MMC):
- board recognizes the usb connection and runs modeswitch which is successfull
- Huawei has issue that ttyUSB is not created and I do it manually by

echo "12d1 1506" >/sys/bus/usb-serial/drivers/option1/new_id
also I make symbolic link to have modem in ttyUSB2 which is hardcoded in init.rc rild starting.
- then rild notices it and runs call-pppd in /etc/ppp/ which I have modified to use bit different chat parameters for my operator.
- from pppd log I can see that chat gets connect, and creation is also visible in logcat:

And then connection is dropped. Does anyone has any idea what happens and what should be done? or any experiences which stick would work?

Answering my own question, but I found out following dongles working right away:

- Huawei E1552
- Huawei E230

And these ones do NOT work working:
- ZTE MF668A
- Huawei E353s-2
- Huawei E3276
