Hi,

I have two Nebula DigiTV master DVB-T USB devices and one slave device.
All three worked in Windows in any combination (so long as a master was also attached if the slave was).

In Linux the two masters work perfectly, I can make multiple recordings off two multiplexes in MythTV. I cannot make the slave work though.

Attached is the output of sudo lsusb -v > digiTV-slave-master-master.txt - Bus 005 Device 008 is the slave and Bus 5 device 006 and 004 are the masters.

Attached is also the end of /var/log/syslog showing the moment the slave is connected. I am interested that the slave device mentions an IR-receiver, I thought only the masters had that (perhaps the salve is only lacking the actual IR receiver component from the PCB).

I can use tzap on all three devices and they achieve lock and report similar signal strength & snr and report ber & unc are both zero.

Currently I have the two master devices plugged in first so they are /dev/dvb/adapter0 and 1, and the slave device plugged in last so it is dev/dvb/adapter2.

The problem I am seeing is that I cannot get any data out of /dev/dvb/adapter2/dvr0.

If I tzap -a 2 -r 'BBC ONE' in one terminal and cat /dev/dvb/adapter2/dvr0 > temp.ts for ten seconds I get a grand total of zero bytes. If I do the same to adapter 0 or 1 I get lots of bytes.

I also have an issue when I unplug the slave device, /dev/dvb/adapter2/* does not disappear and I need to reboot, so I have also attached the end of /var/log/syslog when the device is removed.

Is this a known issue or can I provide any further information to get this working.

Thanks.

Quoted 32 lines · Mark Himsley

Hi,

I have two Nebula DigiTV master DVB-T USB devices and one slave device. All three worked in Windows in any combination (so long as a master was also attached if the slave was).

In Linux the two masters work perfectly, I can make multiple recordings off two multiplexes in MythTV. I cannot make the slave work though.

Attached is the output of sudo lsusb -v > digiTV-slave-master-master.txt - Bus 005 Device 008 is the slave and Bus 5 device 006 and 004 are the masters.

Attached is also the end of /var/log/syslog showing the moment the slave is connected. I am interested that the slave device mentions an IR-receiver, I thought only the masters had that (perhaps the salve is only lacking the actual IR receiver component from the PCB).

I can use tzap on all three devices and they achieve lock and report similar signal strength & snr and report ber & unc are both zero.

Currently I have the two master devices plugged in first so they are /dev/dvb/adapter0 and 1, and the slave device plugged in last so it is dev/dvb/adapter2.

The problem I am seeing is that I cannot get any data out of /dev/dvb/adapter2/dvr0.

If I tzap -a 2 -r 'BBC ONE' in one terminal and cat /dev/dvb/adapter2/dvr0 > temp.ts for ten seconds I get a grand total of zero bytes. If I do the same to adapter 0 or 1 I get lots of bytes.

I also have an issue when I unplug the slave device, /dev/dvb/adapter2/* does not disappear and I need to reboot, so I have also attached the end of /var/log/syslog when the device is removed.

Is this a known issue or can I provide any further information to get this working.

I can confirm that I'm seeing a very similar issue (minus the problems when unplugging and reconnecting the device) with the same hardware. However, I have only one slave device and no master devices, so I'm not able to test in Windows - of course, the slave device should work without restriction (in theory!) in Linux.

With a manually-created "channels.conf" file for the UK / Crystal Palace transmitter (verified with another card) I'm able to use tzap to tune to "BBC ONE", and I receive the following output:

-------------------------
[root@languid adapter0]# tzap -c ~aclark/channels.conf "BBC ONE" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 505833330 Hz

status 1e | signal 000f | snr c6c6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

-------------------------

The channels.conf file is as follows:

-------------------------

Once tuned, "dvbtraffic" produces no output. Cancelling the tzap and running "dvbstream -f 505833 -v 600 -a 601 -o" produces the following debug output:

I should mention that I've never been able to get the slave device working in Linux. I have seen it work in the past in Windows, as at one time I did have a DigiTV PCI card (which is a master device by default in terms of the Nebula software), but the PCI card stopped working long ago due to a hardware fault.

I do wonder if the problem might be with the firmware. However, that's only a hunch and I have no way to confirm either way, mostly because debugging something like that is way out of my league. :)

Mark - Maybe you can do some of the above tests if you haven't already to try and confirm if the issue is consistent for multiple slave devices.

Thanks,

Andy Clark.
