Hmm, what exactly is it you want to know? DVB-USB is layer, which includes some common code (for Linux DVB, USB, I2C, Remote) which is exactly the same between all DVB-USB devices I encountered so far. To your device: I don't think, that you need to implement the control of the tda10046 from the host. I really think that Twinhan put this into the USB-controller (FX2) firmware. (like it is done with the mt352) If you don't understand what this means, well, I'll try: Hmm, instead of writing the email, I put it on a wiki page: http://www.linuxtv.org/wiki/index.php/DVB_USB#Additional_technical_information So, now that you know, that your device is falling into the firmware-controlled devices category, I think the next step is to get the firmware from the windows-driver or discuss with Twinhan, if they can send it. You can use http://benoit.papillault.free.fr/usbsnoop/ to get the log of the windows-driver. best regards, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/ _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
