<br>Are we allowed to redistribute the new firmware, otherwise we probably need to use dvb_get_firmware.pl ?<br>Would be nice to know if the new firmware works with the old stick, I can take it upon me to<br>write a patch for the perlscript that extract the firmware, but I´d like to know if there is need for two different firmwares

email@example.com</a>> who<br>> also has one of these devices.<br>><br>> The firmware can be extracted from the available Windows<br>> driver files. I<br>> think I wrote a script to do this.
<br>><br>> Based on usb snoop data, I was able to write a patch to the<br>> dvb-usb code<br>> so it could distinguish between the two devices. That was as<br>> far as I<br>> got. I don't know of anyone else who has gone any further.
<br>><br>> The next step would be to write the code to download the new<br>> firmware to<br>> the device. My understanding of the existing code base was too<br>> limited<br>> to be able to write this in a reasonable amount of time.
<br>><br>> I wish I had more time and skills for this but perhaps you can<br>> make some<br>> headway. You can have my code patch if it helps.<br>><br>> Regards,<br>><br>
