3G USB modems with DM800/8k?

  • Hello. I want to make working my USB 3G modem with dm8000 but have a problem with correct modem detection. Now it detected by GP 4.0 like USB MASS STORAGE. For switch VID PID to correct one I need usb_modeswitch compiled for mipsel arc...

    Thanks in advance.

  • usb_modeswitch compiled by you run ok on dm8000!!!! :einschenken: Can you explain me how you compile it? I have make "bitbake devshell", then run devshell and run compile.sh...Whats wrong? ;)

    10x thanks!!

  • in the devshell you moust set the path for includes and lib

    mipsel-linux-gcc -I ../../build/tmp/staging/mipsel-linux/include/ -l usb -L ../../build/tmp/staging/mipsel-linux/lib/ -o usb_modeswitch usb_modeswitch.c
  • After usb_modeswitch modem is detected, but no devices like /dev/ttyUSB0..2 created ;( ;(

    here is dmesg from my laptop :

    this is Dreambox :

    Any idea how to make it working?

  • No ideas? ;( ;( Looks like usbserial not work correct..

    cat /proc/bus/usb/devices

  • Check if kernel module usb serial is installed, in my case it was, but internet key doesn't works, same error as you...

  • Sorry to say, but you mostly need special driver files for the serial port as far as it's not a "normal" serial port.
    The maximum port speed is far above "regular" RS232-serial ports (max. 115200 kbaud = 92160 kbit/s at 8 databits, no parity, 1 stopbit) and in so far needs special drivers. The other thing is that the port speed is changed dynamically while the connection is established. Your usb modem uses 2 different ports for communication and control messages - this is mostly not supported by "normal" modem drivers.

    So maybe you think of getting an UMTS router (like the Huawai E960, branded as T-Mobile web'n'walk Box IV).
