Dear Community,
previously I had a Raspi2 with the latest Libreelec (9.2.4) and that DVB stick working, but as it was pretty unreliable, so I wanted to try the a Raspberry Pi 4.
I installed tvheadend and tried to connect to it via my desktop computer's web browser to configure the Channels, but I can't connect to tvheadend.
I then checked tvheadend was properly installed and then I tried all three DVB driver options, but no reply in the tvh browser config winwow
I read quite a bit on related subjects, but - wow - I can't get it all in my head at once!
Maybe Linux is simply a bit too complicated for me 
Under "USB-devices" via SSH, there's the following message:
T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

I: If#= 1 Alt= 0 #EPs= 0 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
It would be great if someone could give me a hint where to continue.
Best regards,
Dominique
PS. I'm just seeing this strange "MxPwr=500mA"
Ths stick is the only USB device and I put it on a USB3 port so I though that should be fine.
