Here is a modified firmware loader for version 2 types.
The firmware must be as in original
./dvb_get_firmware it9135
dd if=dvb-usb-it9135.fw ibs=1 skip=12866 count=5817 of=dvb-usb-it9135-02.fw

I have a 9006 version device.
Just to confirm that this patch and patch 8794 get this device working,
along with dvb-usb-it9135-02.fw as described previously.
Firmware version should be: 52887808
Both can now be submitted to kernel.

Malcolm
