PCTV (ex Pinnacle) 74e pico USB stick DVB-T: no frontend registered
Hello, I've run into a roadblock problem with my PCTV 74e pico USB stick for receiving DVB-T. My setup is as follows: the system is a Kubuntu Kaotic Koala 9.10 stock distribution, kept current. The Linux kernel is thus a 2.6.31-18-generic one as distributed by Ubuntu. It contains the stock kernel video4linux and I also installed the non-free firmware package in order to have the dvb-usb-dib0700-1.20.fw firmware at hand. With this setup, the pico was not even properly recognized (USB VID:DID = 2013:0246). Yesterday I pulled the most recent set of v4l-dvb files of the mercury repository using hg clone http://linuxtv.org/hg/v4l-dvb;. For reasons I yet don't understand, this file set does not include the complete patch from http://linuxtv.org/hg/v4l-dvb/rev/87039167057078a29ca91c1bcd3369977d6ca463 While dvb-usb-ids.h does already contain the PCTV vendor ID as well as USB_PID_PINNACLE_PCTV74E device ID, file dib0700_devices.c does not contain the registration. The patch from the patchset mentioned above does register the 74e together with 73e. The problem now is that after compiling everything (by switching off build of most modules in order to avoid kfifo problems) and installing the new modules I hit the roadblock. Inserting the pico and doing dmesg | grep -i dvb yields: [10650.021155] dvb-usb: found a 'Pinnacle PCTV 74e' in cold state, will try to load a firmware [10650.021170] usb 1-4: firmware: requesting dvb-usb-dib0700-1.20.fw [10650.041879] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw' [10650.840668] dvb-usb: found a 'Pinnacle PCTV 74e' in warm state. [10650.840870] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer. [10650.841284] DVB: registering new adapter (Pinnacle PCTV 74e) [10650.908062] dvb-usb: no frontend was attached by 'Pinnacle PCTV 74e' [10650.908292] input: IR-receiver inside an USB DVB receiver as /devices/pci:00/:00:1d.7/usb1/1-4/input/input21 [10650.908429] dvb-usb: schedule remote query interval to 50 msecs. [10650.908441] dvb-usb: Pinnacle PCTV 74e successfully initialized and connected. It seems that the frontend registration did (silently) fail, at least from the perspective of dib0700_devices.c. Has anyone information whether the 74e shares the same frontend with the 73e?

It seems that the frontend registration did (silently) fail, at least from the perspective of dib0700_devices.c. Has anyone information whether the 74e shares the same frontend with the 73e? The 74e is not a dib0700-based device, my assumption at that time was wrong. For the 74e afaik, there is no LinuxTV driver right now. (IIRC it is a Abilis based design) best regards, -- Patrick Boettcher - KernelLabs http://www.kernellabs.com/ -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I have been working with PCTV for a couple of months, who has worked with Abilis to get a GPL driver out there. The firmware redistribution rights have finally been straightened out last Friday, so keep an eye on the KernelLabs.com blog for an announcement in the near future. Cheers, Devin -- Devin J.
