LibreELEC TBS 5520 SE

garglkarg · April 8, 2017 at 10:43 AM

I've bought the TBS 5520 SE USB box (without remote control) and set it to my librelec (various versions tested) but couldn't get it recognized...

actual installation is the wonderfull 7.0.2.dvb_drivers by CvH / many thx for that built! I tried any "TBS driver" in the DVB Driver Configuration but without any luck / any change just took some time of thinking and a reboot - it does not give any feedback wich one is selected currently?

but the receiver does appear on lsusb only:

of course I "dmesg|paste"d > QCWY but as far as I understand the USB isn't recon' at all! right? It's the same with any TBS Driver so far!

Am I missing some steps? As mentioned this is a fresh install of LibreELEC-Generic.x86_64-7.0.2-dvb-drivers-1.66 without any changes than the DVB Driver Configuration? I tried LibreELEC-Generic.x86_64-8.0.1-digital_devices without success and I missed the DVB Drivers Configuration addon?
May the USB box corrupt? Or does the "SE" in TBS 5520 SE make any difference.

Any help appreciated - CvH ???

meanwhile I changed to 8.0.1 without success... additionally I tried TBS open source drivers and crazycats media build (containing tbs5521) but I cannot load the custom firmware because of missing module... dvb-usb-tbs5520 exists but does not load the tbs 5520 se...

verbose lsusb told me

dvb-usb-tbs5520se.

Driver not tested, so if you have some PC with regular linux (desktop or server) and can provide remote access ... I can checkmand debug driver for 5520se.

dvb-usb-tbs5520se.

where do I get this driver? could not find it in compiled media_build...
is it fair just to copy the ko beside dvb-usb-tbs5520.ko?

sorry i'm not able to give remote access through current firewall settings...

whoooop whoop I'm excited!! BUT obviously my Ubuntu (kernel 4.4.0.72) isn't the LE... I cannot test it any further
sooo, how do I get this wonderful driver to my LE installation (currently 8.0.1 with kernel 4.9.x)??

**crazycat** · April 17, 2017 at 7:06 PM

Wait updated LE 8.x build

ok, so it gets in the official head? great!

thank you very much for your help! makes this project real fun!

I have this device and am trying compile driver from github for armhf platform - no success. Did someone successfully compile a functional driver?

yes I did! but on my generic intel pc with Ubuntu installed. got the usb box running with compiled crazycat drivers - it overrides my Nvidia and it had some crashes in the beginning but everything works fine now. have my tvheadend up and kore running.
I'm very pleased and satisfied!

sorry pinging ppl with @Name don't work (new board soon that fix that) so I never saw this thread before

Generic 8.0.1 LibreELEC-Generic.x86_64-8.0.1-tbs5520.img.gz

with that patch applied - if someone could confirm that this fixes the 5520 would be great (pr to next LE8 release)

Sorry to bump old thread. Was considering to buy a TBS 5520 SE. Anyone can tell me if now it works with Libreelec? Wanted to know also if in Tvheadend there are two tuners (dvb-t and dvb-s) that are switched on the fly, or if we have to switch by sotftware the tuners before using them (as in windows).

Thnak you,

this is no LibreELEC problem more a general driver problem - as long none reports something back you can expect it as NOT working

sdf · June 8, 2017 at 7:02 AM

saw that was supported with open source drivers in the tbs forum.

If anyone has bought it and can report back

Thank you CvH,

sdf

Solved. Bought a Mygica (Geniatech) Hdstar. Perfectly supported.
