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

[10650.908441] 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?
With best regards,
