opensource drivers issue

[steven]

Hi

Maybe you can have a look at this user guide for multi-standard card use way .
http://www.tbsiptv.com/download/tbs6522 ... -users.pdf

Thanks

Kind Regards

Thanks for your answer but the result is the same: I cannot tune DVB-T with TBS 5520 in kernel 4.x.

An excerpt from tvheadend:

2016-11-03 23:44:47.000 mpegts: 522MHz in TBS5520 DVB-T - tuning on Availink AVL6882 : DVB-T #0
2016-11-03 23:44:47.000 subscription: 0300: "scan" subscribing to mux "522MHz", weight: 6, adapter: "Availink AVL6882 : DVB-T #0", network: "TBS5520 DVB-T", service: "Raw PID Subscription"
2016-11-03 23:44:52.000 mpegts: 522MHz in TBS5520 DVB-T - scan no data, failed
2016-11-03 23:44:52.000 subscription: 0300: "scan" unsubscribing

The same for other known mux from my TV area. I'm still thinking that there's a problem with open source drivers in 4.x kernels but I don't know why ...

Thanks.

Hello,

open source drivers for TBS5520 by CrazyCat (https://bitbucket.org/CrazyCat/) are still not working under Fedora Workstation 26. Next I report the issue following forum instructions:

- Description of the problem: compilation runs fine. The steps followed are:

Code: Select All Code

git clone https://bitbucket.org/CrazyCat/media_build.git
cd media_build
./build
sudo make install

- After reboot the system or plug/unplug the USB the systems logs are (journarctl --follow):
