Perfect, I`m currently writing a parser in perl that converts the new firmware that ´ve extracted from the windows file to the "same" format that is used in the old vp7045 card. I´ve enhanced the dvb_usb_get_firmware.pl to download and extract the new vp7045 firmware from the windows driver, but either the load code needs to be rewritten or the firmware reformatted, both will probably work but I don´t know wich one is the best way to go. The new stick has a lowpower version of the FX2 usb controller, so the current loader "should" work, but I think it needs to load the firmware in chunks of 64 bytes (this is how windows does it) instead of one 8192 byte chunk as the current formatting tells windows (this is why I´m converting the firmware, to verify this theory).
"Based on usb snoop data, I was able to write a patch to the dvb-usb code so it could distinguish between the two devices. That was as far as I got. I don't know of anyone else who has gone any further." That patch would be very very good for me. Any information you can supply me with is greatly appriciated. Also do the old cards work with the new firmware ? If or when we get a firmware on the stick do we need to attach another modified frontend to handle the TDA10046 or will that be the end it ? /Henrik On 4/13/07, Chris Wylie <[EMAIL PROTECTED]> wrote:

In fact I have a pair of vp7045 tuners, one with the mt352 and one with the tda10046 (very useful to make comparisons). I tried to make it work last year. I got some good information but no solution and had to put the project aside due to lack of time and expertise. Here is what I know. The vp7045 with tda10046 needs a firmware download that the current dvb-usb code does not know about. Patrick Boettcher <[EMAIL PROTECTED]> knows the existing vp7045 code and was able to assist by getting some limited information from TwinHan. We also exchanged some emails with Stewart Smith <[EMAIL PROTECTED]> who also has one of these devices. The firmware can be extracted from the available Windows driver files. I think I wrote a script to do this. Based on usb snoop data, I was able to write a patch to the dvb-usb code so it could distinguish between the two devices. That was as far as I got. I don't know of anyone else who has gone any further. The next step would be to write the code to download the new firmware to the device. My understanding of the existing code base was too limited to be able to write this in a reasonable amount of time. I wish I had more time and skills for this but perhaps you can make some headway. You can have my code patch if it helps. Regards, Chris
