Comment 1 Wolfgang Ulbrich 2019-04-02 10:21:20 UTC
[    8.604045] usb 5-2: Direct firmware load for dvb-usb-technisat-cablestar-hdci-drxk.fw failed with error -2

This can be ignored. This goes away if i install the firmware.
But the device works without installing firmware from https://linuxtv.org/wiki/index.php/TechniSat_CableStar_Combo_HD_CI  .

Comment 2 Wolfgang Ulbrich 2019-04-09 09:13:31 UTC
Can this commit be removed for fedora please?
People starts filing out reports against kaffeine at rpmfusion? https://bugzilla.rpmfusion.org/show_bug.cgi?id=5227
