>hi I type the modprobe drxvi314 the modem starts flashin but pc just hangs up???

check your usb voltage, first. Maybe you don't have enough power? Cause i had some problems.

>and i use ubuntu 10.10.

hamid! What version of kernel is you have?
Is drxvi314 compilation goes well?

There is a patch applyes during installation. For kernels above.. i don't remember. But if you what to try without this patch you can do this

1. After extracting Sprint4GDeveloperPack-1.1.tar.gz open install.sh with editor
2. find
--------------------------------------------------

      cd $SRC_DIR/$BECEEM_REV_DIR/Source/Driver/Network/OSAL/Linux/usb
      pm "\nConverting any DOS linebreaks (grrrr Beceem)..."
      for f in `find . | grep \\\\.h`; do tr -d '\15\32' < $f > $f.conv; mv $f.conv $f; done
      for f in `find . | grep \\\\.c`; do tr -d '\15\32' < $f > $f.conv; mv $f.conv $f; done

      pm "Patching Beceem kernel module..."
      cd $SRC_DIR/
      for pf in `ls $RUN_DIR/patches/$BECEEM_DRIVER`; do
    patch -p0 < $RUN_DIR/patches/$BECEEM_DRIVER/$pf
      done

      cd $SRC_DIR/$BECEEM_REV_DIR/Source/Driver/Network/OSAL/Linux/usb
      pm "Building Beceem kernel module and driver..."
      make default
      make install
      depmod -a
----------------------------------------------------------------------------
and remove it, save changes

3. start installation
./install.sh
It will build and copy everything except patching, compiling and installing drxvi314.ko

4. type in terminal lines below to compilate and install drxvi314.ko
cd /usr/src/USB_350/Source/Driver/Network/OSAL/Linux/usb
sudo make install

after that you can use 'sudo modprobe drxvi314'
