i have the Problem that with the newest Raspbian a HUAWEI E3531 not works, well her boots on the Card Slot.
Then i have update usb-modeswitch with apt-get install from deb http://ftp.debian.org/debian jessie-backports main.

That works ! The HUAWEI E3531 can i use on a Raspberry Pi 2.
But when i Plug the SD Card into the Zero it comes a error on boot.
And usb-modeswitch newest Version not works.
The older usb-modeswitch from the Raspbian works. But not for the HUAWEI E3531.
