Hi Andrea, About one year ago I started to work on it, but gave up because I haven't had any information about demodulator and tuner. This completely changed now, because, as you correctly stated, every single piece of the "Frontend" is now supported. I have some information about the FX2 for this device, but it is 1 year old and has maybe changed. I extracted the firmware using the windows driver and usbsnoop. I called the file "dvb-usb-pctv-400e-01.fw", but didn't make it public. I started to implement the firmware interface in the driver, by knowing that the interface is almost similar to the ttusb-interface. I think I still have the corresponding dvb-usb-code at home - I'll take a look. However I also heard, that there are some problems with the device, hardware or software (Windows). Maybe in the meantime there is a new Windows-driver from Pinnacle, which is changing the whole firmware-interface (instead of isochronous maybe bulk is used, maybe also some requests). To figure that out, one needs to do more usbsnooping. Hope that helps, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/ On Tue, 8 Aug 2006, Andrea Venturi wrote: > hi, > > recently i got a pinnacle pctv400e on my hands.. > > http://www.pinnaclesys.com/images/design/boxshots/box_wd_pctv400e.jpg > > i tried with yesterday (7.8.06) SVN drivers from linux-dvb, but it seems > still not recognized. > > there's an ugly shot of the inside here: > > http://www.cineca.tv/assets/img/pctv400e.jpg > > but i see on the wiki that's something is already going on: > > http://www.linuxtv.org/wiki/index.php/DVB_USB#Pinnacle_PCTV_400e_USB2.0_DVB-S > > there's already a BOM of the chips; i just can add that the usb > controller is a cypress 7c68013 [*] i.e. a ez-usb fx2 clone, if i'm not > wrong.. > > i can already see all the modules (frontend, modulator, etc..) in > the linux-dvb tree.. > it's just a matter to put all together with the right strings :-) > > so, maybe, there's only some wiring to be detected to get the linux > driver working.. is it right? > > BTW the device at least work on the winXP; maybe i could dump some usb > transactions, if it helps > > BTW2 i see there's a firmware to be uploaded to the box: > > dvb-usb-pctv-400e-01.fw > > but i didn't find it anywhere. > > anyway, the box seems to stay hot (warm..) if i reboot from windows to > linux, because the onboard led remains green (and not red as in a cold > state); you can find, below, both the cold and warm (warm.txt) "lsusb > -v" output, they look a bit different > > > so, who knows what is missing and what can be done to put on the right > linux track this device > > > bye > andrea venturi > > > > [*] cypress page and datasheet > > http://www.cypress.com/portal/server.pt?space=CommunityPage&control=SetCommunity&CommunityID=209&PageID=259&fid=14&rpn=CY7C68013 > > _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
