Vu+ Duo2 Tuner B problem with Sundtek as Tuner C

[CuriousCorn]

Hi all,

I see that my issue has been discussed before, but the thread concerned did not give any final conclusion. So, I start a new thread.

I have a Vu+ Duo2 with the OpenPLI 4.0 latest image, with a USB Sundtek tuner installed as Tuner C and the latest Sundtek drivers installed.
 
All of the tuners (the two internal ones, A & B and the Sundtek, C) should be allocated to DVB-C.

But, Tuner C (Sundtek) appears to be in conflict with the internal Tuner B. If I set Tuner C to be DVB-C, then Tuner B resets itself as DVB-T (which is of no use), with the result that Tuner B then fails with "Tune Failed"

If I then set Tuner B as DVB-C, Tuner C then resets itself to DVB-T2..

As a result, I cannot seem to be able to set all three tuners to DVB-C! At one point, I was able to set all three as DVB-C, but then after a hard reboot, Tuner B came up as DVB-T. But, when I go into Tuner Configuration and select Tuner B it says it's DVB-C (which it is not). To get it back, I have to set it to DVB-T, click OK, then select DVB-C again. But then Tuner C goes to DVB-T!

I have re-installed the Sundtek drivers, but this made no difference.

Is there somewhere a configuration conflict, or something? Possibility that it's something on Sundtek's side? Might seem likely, given what I have to do to get Tuner B back to DVB-C. Why would Tuner B suddenly re-invent itself as DVB-T after a reboot?

I removed the Sundtek USB tuner last night, and then Tuners A and B were fine; both on DVB-C. I put the Sundtek back in, and then Tuner B got unhappy and went to DVB-T!

Please advise if I should send any further information that may be useful, or if you have any advice as to what I could do.

Thanks in advance and best regards,
CuriousCorn

Did you install the driver using the Windows-Settopbox Installer?

Can you show us the output of following telnet command on the Settopbox

cat /proc/bus/nim_sockets

when things are not as you would expect them to be?

Hi Sundtek,

I did the installation with the Mac OS X installer.

Output from cat /proc/bus/nim_sockets (With Sundtek attached; Tuner B is showing DVB-T):

root@vuduo2:~# cat /proc/bus/nim_sockets
NIM Socket 0:
        Type: DVB-C
        Name: Vuplus DVB-C NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T
        Frontend_Device: 0
        I2C_Device: 2
NIM Socket 1:
        Type: DVB-T
        Name: Vuplus DVB-T NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T

NIM Socket 2:
        Type: DVB-C
        Name: Sundtek DVB-C (III) (0/0) (USB)
        Frontend_Device: 2


This is the output when I set Tuner B to be DVB-C:

root@vuduo2:~# cat /proc/bus/nim_sockets
NIM Socket 0:
        Type: DVB-C
        Name: Vuplus DVB-C NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T
        Frontend_Device: 0
        I2C_Device: 2
NIM Socket 1:
        Type: DVB-C
        Name: Vuplus DVB-C NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T
        Frontend_Device: 1
        I2C_Device: 3



NIM Socket 2:
        Type: DVB-C
        Name: Sundtek DVB-C (III) (0/0) (USB)
        Frontend_Device: 2

This is the same, but after a reboot:

root@vuduo2:~# cat /proc/bus/nim_sockets
NIM Socket 0:
        Type: DVB-C
        Name: Vuplus DVB-C NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T
        Frontend_Device: 0
        I2C_Device: 2
NIM Socket 1:
        Type: DVB-T
        Name: Vuplus DVB-T NIM(CXD1978)
        Mode 0: DVB-C
        Mode 1: DVB-T
        Frontend_Device: 1
        I2C_Device: 3



NIM Socket 2:
        Type: DVB-C
        Name: Sundtek DVB-C (III) (0/0) (USB)
        Frontend_Device: 2


Thanks and best regards.

Ok, this is very likely a topic for an OpenPLI developer. I forwarded it to pieterg in the openpli forum since he seems to be involved with the latest OpenPLI changes.

OK, thanks, let's see what happens

let's stop this discussion here and continue in the openpli Forum with that, I think this is something that might affect OpenPLI and not our tuners but let's see.
Better to have the other guys involved.

For the record:

seems like this issue has been in the forum already but your post gives most details about the problem so far:
