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!
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!
wonderful! thank you!!
compiled on my Ubuntu machine, installed it's drivers and rebooted!

garglkarg@obelix:~$ uname -r
4.4.0-72-genericwhoooop 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)??
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...
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...

bNumConfigurations 15520se anyway not supported in old linux-tbs-drivers (only restricted 5520 support as sat tuner only).
So you must use LE 8.x +
ok, i didn't know that - even sat support only would be satisfying for my LE start.
so final question: would your media_build firmware work in LE 8.x+ and what do I need to load the custom firmware, modprobe what?
maybe you use before 7.x with my linux-tbs-drivers ?
ok, I did... but without success I used the CvH 7.0.2 image, with tbs5520se plugged in, selected TBS CrazyCat driver in DVB Driver Configuration, loaded the tar.bz2 just copied the ...tbsqbox-id5521.fw into the /storage/.config/firmware and modprobed the most similar module dvb-usb-tbs5520(.ko) but without any further response... still no dvb adapter in tvheadend 4.2 addon
dmesg told me

thx for any assistance!
many thx for ur information crazycat moves me forward!
In my linux_media repo 5520SE required dvb-usb-tbsqbox-id5521.fw
linux_media/tbs5520se.c at latest · crazycat69/linux_media · GitHubAnd dvb-usb-tbsqbox-id5520.fw for 5520
linux_media/tbs5220.c at latest · crazycat69/linux_media · GitHubAll required firmware in dvb-firmwares.tar.bz2 @ my media_build
sorry, i don't get it... i loaded the tar.bz2 just copied the ...tbsqbox-id5521.fw into the /storage/.config/update/firmware of my current 8.0.1 (or is 7.0.2 needed for these firmware files?) installation of LE
the nearest module to load was dvb-usb-tbs5520(.ko) where modprobe succeeded and dmesg messaged:
[ 1341.756091] WARNING: You are using an experimental version of the media stack.

for me it seems that the firmware file is not enough... I need the module (.ko) file as well but where from?
I think 5520se supported, by not tested. I have only 5520 sample (avalink demod based)
thx for info - dumb question but am I missing any steps? 
just installed LE, plugged usb tbs5520se in and selected some TBS Driver in DVB Driver Configuration. meanwhile I tested some other images (incl. CvH 8.0.1 test images) without any success. 
do i have to modprobe some modules? just read this for some other cards/boxes?
I recognized that an firmware dvb-usb-tb5520. fw exists in LE. latest from TBS includes dvb-usb-tbs5520-01.fw instead - but it did not give any success either... drives me crazy :s
I may have posted in the wrong Forum/Thread... sorry!
so for the CvH image is the TBS 5520 SE supported or not? the TBS 5520 is reportedly working fine, but the SE (without remote control) seems to be missing... my current LibreELEC-Generic.x86_64-7.0.2-dvb-drivers-1.66 with TBS driver installed "dmesg|paste"d > QCWY
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:

uvesafb 18907 1of 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 ???
