AVerTV Volar Green HD DVB dongle doesn't work

Tested with the 8.95.0 release on my Mecool Pro+ (S905X - 2 GB of RAM). Here is what I get with dmesg|grep dvb:

Always publish complete log. Partial logs are useless.

Sorry about that. Here is the complete log:

In the CE 8.95.0 is missing support for mm88ds3103. Install this crazycat version driver.dvb.crazycat-9.0.0.zip. Don’t forget, after upgrading to next CE version, you have to remove this version to be able use newer version.

rm -rf /storage/.kodi/addons/driver.dvb.crazycat

Uukrul · 15 August 2018 17:36

Same problem:

afl1 · 15 August 2018 21:03

Another test version driver.dvb.crazycat-9.0.0a.zip.

Uukrul · 15 August 2018 22:04

Still the same:

I also tried the LE default drivers (I can’t use them because my DVBSky S960 isn’t supported) and those also don’t work (the dvb adapter isn’t created):

btw: do you know if the Xbox One Digital TV Tuner works with CoreELEC? It works with LibreELEC, but I have to be sure before buying one in case I can’t use my AverTV.

Xbox One have to be supported in crazycat and hauppauge.
Current version media_build used by crazycat have lot of recoded drivers for linux 4.x version incompatible with 3.14. There are backports to support legacy linux versions, but there is no guaranty if they works. I reverted crayzcat to previous version. I gained support for AF9013 based DVB-T stick in crazycat. Try this version, support have be close to LE 8.2.

No luck:

I found issue crashing driver. There is race condition between dvb-usb-it913x.ko (kernel) and af9033.ko (crazycat). This was introduced by dvb-driver-addons. There is used kernel-overlays to switch between different module versions with the same name, but issue comes when support is moved from one module to another. This is the case of it913x. Support was moved from dvb-usb-it913x.ko to af9033.ko. To fix this we have to disable build driver for this chip in kernel.

afl1 · 16 August 2018 18:03

Sorry wrong build. I removed link.

Fixed test build:
CoreELEC-S905.arm-9.0-devel-1534445300.tar

Uukrul · 16 August 2018 20:28

Yes, it’s working now!
Many, many thanks for the great support.

Here is the log if you want to take a look:

Also THX for reporting, we fixed hidden bug in dvb-drivers-addons. The fix is pushed already for next releases.

I can confirm that the Xbox One Digital TV Tuner works with CoreELEC 8.95.2 and crazycat-9.0.0prev.

It’s great value for money in case you need a DVB-C stick (10€ in Germany).
