Sorry that I missed your update.

I think it maybe a compatibility issue between the driver and kernel 3.10.

Is it mandatory for you to use Direct IP?
If not, one quick workaround is to change the USB configuration to “3” or “5”.

AT!UDUSBCOMP=?
0 - HIP  DM    NMEA  AT    MDM1  MDM2  MDM3  MS  NOT SUPPORTED
1 - HIP  DM    NMEA  AT    MDM1  MS              NOT SUPPORTED
2 - HIP  DM    NMEA  AT    NIC1                  SUPPORTED
3 - HIP  DM    NMEA  AT    MDM1  NIC1            SUPPORTED
4 - HIP  DM    NMEA  AT    NIC1  NIC2  NIC3      SUPPORTED
5 - HIP  DM    NMEA  AT    ECM1                  SUPPORTED


OK
AT!UDUSBCOMP=3
OK
AT!RESET
OK

In this case, 5 virtual ports will be enumerated (e.g. ttyUSB0 to ttyUSB4), in which ttyUSB3 is the AT port and ttyUSB4 is the PPP port.

I will check using kernel 3.10 within this week.

Thx.
