The huawei modem needs some initialization that is explained here. I have compiled it into a static version.

Next to that, the huawei modem needs a decent compiled usbserial module that accepts overrides. I've recompiled that part also.

• usbserial.o: usbserial that accepts vendor and product parameters
• huaweiAktBbo.static: static compiled version of mode switcher

"howto"

rmmod cp2101
rmmod usbserial
rmmod usb-storage
./huaweiAktBbo.static
insmod ./usbserial.o product=0x12d1 vendor=0x1003

• huawei.tgz: Complete solution to be extracted in /root/

compile howto

Modem switcher:

Make sure you have a working debian/etch on mipsel.

aptitude install libusb-dev gcc
gcc --static -o huaweiAktBbo.static huaweiAktBbo.c -lusb

Kernel module

Make sure you have a working debian/unstable i386 system. Put this in your /etc/apt/sources.list:

deb http://www.emdebian.org/debian/ unstable main

Then aptitude update and aptitude install the following:

gcc-3.3-mipsel-linux-gnu uboot-mkimage

Have the kernel source from the trendtac site unpacked and patched. Patch the Makefile so it will accept:

export ARCH=mipsel
export CROSS_COMPILE=mipsel-linux-gnu-

Make the default configuration by: "make defconfig-pmpv2", and select usb/serial/generic from the make menuconfig. make dep uImage modules will give you a bootable uImage and modules.
