Try using the following for firmware.

dd if=dvb-usb-it9135.fw ibs=1 skip=64 count=8128 of=dvb-usb-it9135-01.fw
dd if=dvb-usb-it9135.fw ibs=1 skip=12866 count=5731 of=dvb-usb-it9135-02.fw

I have got length of dvb-usb-it9135-02.fw wrong it was changed to 5731.

However, 5817 should be correct in emulation, but fails with device.

The firmware version should say it913x: Firmware Version 50594048

I will have to check the firmware loader again.

Regards
