  • Does this dvb s2 tuner work?

    tried some distro kernels on my Intel NUC (HD Graphics 4400 (GT2) supported by kernels elder than 4.x.y (no go for my Desktop (Intel HD Graphics 530 => black screen):

    Ubuntu 16.04 LTS now as 16.04.04 has kernel 4.13, found no elder CD so far, scratched

    Debian 9 has kernel 4.9.0.6: crashes with NULL pointer ..., scratched

    Fedora 24(has a lot of kernels available; sweet):

    4.5.5: release kernel, does not load any module after plug in the device, no dvb-usb-$something, nothing...

    4.9.4 crashes with NULL pointer ...

    4.8.16 crashes with NULL pointer ...

    4.7.2 crashes with NULL pointer ...

    more next days ...

    Quote from CvH

    currently not yet an idea how to activate the logging

    I'm just an dam'ol' user, no developer, but -IFAIK- m88ds3103 has no parameter (modinfo m88ds3103)

    maybe dvb-core could do the job ?

    modinfo dvb-core:

    ...

    parm: frontend_debug:Turn on/off frontend core debugging (default:off). (int)

    parm: dvb_shutdown_timeout:wait <shutdown_timeout> seconds after close() before suspending hardware (int)

    parm: dvb_force_auto_inversion:0: normal (default), 1: INVERSION_AUTO forced always (int)

    parm: dvb_override_tune_delay:0: normal (default), >0 => delay in milliseconds to wait for lock after a tune attempt (int)

    parm: dvb_powerdown_on_sleep:0: do not power down, 1: turn LNB voltage off on sleep (default) (int)

    parm: dvb_mfe_wait_time:Wait up to <mfe_wait_time> seconds on open() for multi-frontend to become available (default:5 seconds) (int)

    parm: cam_debug:enable verbose debug messages (int)

    parm: dvb_demux_tscheck:enable transport stream continuity and TEI check (int)

    parm: dvb_demux_speedcheck:enable transport stream speed check (int)

    parm: dvb_demux_feed_err_pkts:when set to 0, drop packets with the TEI bit set (1 by default) (int)

    parm: debug:Turn on/off debugging (default:off). (int)

    parm: dvbdev_debug:Turn on/off device debugging (default:off). (int)

    so, I tested LE 8.2.4: same bug as in #57 with LE 8.2.3.

    it's not surprising, cause none, whether milhouse nor release running kernels beginning with 4.15.8 where the patch which prevents "NULL pointer dereference" is in !

    to sum it up (please correct if I'm wrong)

    (newer, since ~ beginning 2018) Technotrend TT-connect S2-4600 and Terratec Cinergy S2 USB BOX do NOT run under LE und other distro's.

    It seems that the internals for this devices are undocumented changed so there is currently (march 2018) no driver support or bugs in the kernel.

    This situation may somewhat, but not sufficient, improve if LE or distro's runs kernels beginning with 4.15.8.

    It has to be mentioned that kernel 4.15.8 - IFAIK- only filters out a kernel crash, but does not fix the underlying problem (bug fix, improved driver support)

    I suggest to make this statement somehow sticky in LE Forum, so everybody can easily (without searching/reading through long threads) read this, before buying a useless device.


    My intention is to lower or to prevent user pain, that's all.

    My intentions is not to blame or to harm developers or supporters of LE/distro's !!!

    P.S.

    maybe I find a way to publicize my view/findings at dvb wiki...

    So, I got 13 days left to test.

    Any hints ?
