In my dmesg I get:

[    7.581993] si2168 11-0064: Silicon Labs Si2168-B40 successfully identified
[    7.581997] si2168 11-0064: firmware version: B 4.0.2
[   19.780406] si2168 11-0064: firmware: direct-loading firmware dvb-demod-si2168-b40-01.fw
[   19.780409] si2168 11-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
[   20.372170] si2168 11-0064: firmware version: B 4.0.4

Apperently I need to get a newer version.
