Hauppauge WinTV-SoloHD USB device on Vero4K

Hi, my vero now runs with version 2017.05-2 and it seems to download the required firmware:

dmesg
...
[   17.697108] si2168 2-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
[   17.915062] si2168 2-0064: firmware version: B 4.0.11
[   17.920923] si2157 3-0060: found a 'Silicon Labs Si2157-A30'
[   17.969018] si2157 3-0060: firmware version: 3.0.5

However, after configuring the device in tvheadend I was not able to find any channels. Probably this is the same problem you have @brevilo ?

After disabling tvheadend server I ran a locally compiled w_scan and get this:

./w_scan -ft -c DE 
w_scan version 20170107 (compiled for DVB API 5.10)
using settings for GERMANY
DVB aerial
DVB-T Europe
scan type TERRESTRIAL, channellist 4
output format vdr-2.0
WARNING: could not guess your codepage. Falling back to 'UTF-8'
output charset 'UTF-8', use -C <charset> to override
Info: using DVB adapter auto detection.
WARNING: YOU ARE USING OUTDATED DVB DRIVERS.
        /dev/dvb/adapter0/frontend0 -> "Silicon Labs Si2168" doesnt support TERRESTRIAL -> SEARCH NEXT ONE.
main:4007: FATAL: ***** NO USEABLE TERRESTRIAL CARD FOUND. *****
Please check wether dvb driver is loaded and
verify that no dvb application (i.e. vdr) is running.

Now, I am running out of ideas.
Suggestions, anyone?
