Hello,

I have a Logilink VG0022A stick and when I plug it in I get:

[  426.019171] usb 1-1.3: new high-speed USB device number 5 using xhci-hcd

which looks fine. But when I try to use it (using mumudvb2) I get:

[  480.496756] si2157 10-0063: firmware version: �.�.255

and it fails to tune.

Do you have a hint?

Best regards
Uwe

  That is to be expected, the device provides its own (patched?) firmware. This output is very
  similar to what I have and it works fine. Tested reception on both DVB-T standards with
  kaffeine, mumudvb2 tip and t2scan. You'll see the second part of dmesg message each time
  You'll switch the channel or start tuning.

  What differentiates between Your configuration and mine is I tested the stick in USB 2.0
  port. Also what I'm missing from Your log is loading of dvb-demod-si2168-02.fw, I assume
  it's present, since the driver doesn't complain.
  I don't know if it's enough of a hint, since I'm not 100% sure if my TerraTec TC2 Stick is
  exactly the same as VG0022A, but hope it helps

  Never mind. I use a different anntenna now, and it tunes in just fine

    Guten Tag Uwe,
    
    What does the signal level and CNR look like?
    Not sure if your TV viewer app can display those stats.
    The femon plugin in VDR can do it.
    There are command-line tools that can show these stats:
    https://linuxtv.org/wiki/index.php/Dvbv5-zap
    https://linuxtv.org/wiki/index.php/Dvb-fe-tool
    I am slightly sad that these tools show signal level in %, rather 
    than dBmW or dBuV.
    
    In my experience with a single dongle (the T230C2), CNR of 25 dB is 
    barely okay. I've never seen a CNR better than say 38 dB.
    
    Frank
