@Debrau please attach your screenshots to this issue rather than opening another.

@ Debrau Nepasat
Can you connect your tuner via external powered USB Hub,
and see if there is a difference.

Hello Mark,
Will do! Sorry for that, my mistake!

Hello saen acro,
I will try that, I have first to get a USB Hub because I do not have one. Can you recommend something you have made good experience with?
Thanks!

Note that all USB DVB-S tuners should be powered using an external power source (adapter). The USB hub is not necessary, if you use this power source.

Hello, the Tuner has an external power source (it's own), it is not using the USB power. By knowing that you still recommend to try with a USB Hub powered separately? Thanks.

External power source power only tuner and LNB
at less my terratec work at this scenario
USB power only modulator IR and CI

Easy to test when attach to usb only without external power

Hello saen acro, I have checked the USB power consumption, please see below:

lsusb -v|egrep "^Bus|MaxPower"

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
MaxPower 0mA
Bus 003 Device 002: ID 1058:1042 Western Digital Technologies, Inc. Elements SE Portable (WDBPCK)
MaxPower 224mA
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
MaxPower 0mA
Bus 001 Device 002: ID 0b48:300d TechnoTrend AG TT-connect CT-3650 CI
MaxPower 10mA
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
MaxPower 0mA

MaxPower 10mA seems not to be more than usb 2.0 can handle, what do you think?

dmesg command and log situation when plug usb with and without external power
and when CI active/inactive

Hello, need to get an external powered USB hub first, will post after. Thanks.

Hello together again,

Finally I have managed to try again after buying a USB Hub with external power.
Unfortunately I get again the same error as I got without the USB hub, please see below log:

Is there any workaround for that?

Have also tried with the newest TvH and the same...

Any opinion or idea?

What hardware are you using? What OS/linux kernel version?

May be related to this:[[https://tvheadend.org/boards/13/topics/26397]]

Have you tried unplugging and the plugging in the module while tvheadend is running? (as opposed to a USB reset)

Have you tried disabling then enabling the module through the tvheadend web interface?

I tried to unplug and plug back while TvH running with no luck. What happens is that initially the CA is identified as present and within 10 seconds it goes back to not present.
I have also tried to disable and re-enable with no luck.
Any further ideas?...I cannot get it to work

Forgot to mention the Kernel version witch is 4.4.92
