Added by Carsten Johansson over 5 years ago

Hi
I have reinstall my ubuntu and tvheadend and have now a Little problem

I have a TBS 5880 USB and I have install with the Close drivers and it looks like Everything is ok

When I run

sudo dmesg | egrep "dvb|frontend|firmware"

I get this

[    0.009756] Spectre V2 : Enabling Restricted Speculation for firmware calls
[   14.191790] dvb-usb: found a 'TBS 5880 CI USB2.0' in cold state, will try to load a firmware

but when I trying to mux I get nothing in the tvheadend.
It just say

Scan result = PEND
Scan result = NONE

when I run

w_scan -ft -c SV >> channels.conf

I can see it find my mux frequency/transponder
It say when it scan

514000: (time: 00:36.868)         signal ok:    QAM_AUTO f = 514000 kHz I999B8C999D999T999G999Y999 (0:0:0)
        Info: no data from PAT after 2 seconds
        deleting (QAM_AUTO f = 514000 kHz I999B8C999D999T999G999Y999 (0:0:0))

but when is finnish it say

ERROR: Sorry - i couldn't get any working frequency/transponder

and give me a empty file.

Have no idea what to do now??

With Ubuntu and with kernel?
This is normal for TBS.
Software part under linux need complicated modified kernel modules,
as result when this start to work other will stop and vice versa.

Xubuntu 16.04 and kernel 4.4

I have read that the driver have problem with kernel that is new then 4.10 so I running a old xubuntu and old kernel.

Have follow the guide that they have show and I have got it to work before but not now?
