GB UE 4K: USB Tuners not working

[AbuBaniaz]

USB tuners are not working on the the GB UE 4K. They install correctly. Scanning does not find any channels. If you add lamedb file with them included they do not tune.

This is for both Terrestrail and Cable. I tested this in the UK. The PnP tuner works fine.

I have tried an Xbox USB tuner, Sundtek, as well as an August tuner, same result.

I have tested on OpenVix developer image, OpenPLi developer image, OpenATV 6.3, 6.4 and 6.5 image as well as PurE2 images. As you usually ask people to test Team Blue images, I tested that too.

To repeat post by white whistle: https://www.world-of-satellite.com/showthread.php?64135-Can-you-use-USB-DVT-T-(PlayTV)-as-extra-tuner-with-Gigablue-UHD-stbs&p=512566&viewfull=1#post512566

Basically I am trying to get a Sony PlayTV usb dual dvb-t tuner working on this box - it uses the dib0700 driver pack.

Box came with Teamblue 6.4 installed, so installed the drivers, rebooted, configured them, but a scan returned nothing!
Tried the oldest version of 6.4 as well as the 6.3 versions - nothing scanned.

Decided to install the extra dvb-s2x tuner in the pnp slot, and tried the images again - no change.

So downloaded all the images from openpli, openvix, openatv, teamblue and openhdf I could find taking the oldest/latest from each major version.

For each I did the following:-
fresh flash, no restore, minimum configuration (display + network), downloaded dib0700 drivers, rebooted, configured dvb-t tuners and attempted scan.

All failed to scan and find anything except 2
openvix 5.1.003 20180828
openpli 6.2 20190512

Both found all the channels on the 2 tp/channels we have in Ireland.

Common thing between them, is that both used the drivers from 20180405.
Did a checksum on the driver files in each image, and they matched exactly.

Using the github history on the gigablue-platform-util-gb7252.bb file, I could see the next driver pack was dated 20180914.
This coincided with a change in the bcm sdk

[GigaBlue | gb7252] update build

* Update drivers to new BCM SDK
* add opengl Support
* add Kodi Support
* add Chrome-WEB Browser
* add Youtube.TV
* add Bluetooth Audio Support (need optional BCM Bluetooth USB Adpater)
* add QT HBBTV Support
* add Support for new Gigablue DVB-S2X Single and Dualtuner with Multistream
* update LCD modes to only support regular modes (no more pip in lcd)
* Info: Quadpip at the moment only supports 1080i and 2160p as video resolution (the fix to support 720p and 1080p is coming later)
* remove support of 480 and 576 video resolution - new BCM SDK dropped that
Had a look at the driver pack, and it's also the first occurrence of the file dvb.ko, so its a different set of files than the working set.

Not sure if it means anything, but for all the images I tried (except 1 openhdf), the tuners were recognised, they could be configured, and using the Signal/Satellite panel, the tuner could be selected, so could the 2 tps/channels, and in each case a signal level was detected and a signal lock was shown.

As you have a new driver technician, I am hoping some traction can be made.

On this test, I have used a Sony Play USB tuner. Just to prove the USB tuner is working, here is a log of it scanning on a Vu Duo 4K using ATV, there is no PNP terrestrial tuner vu duo 4k atv no pnp_usb scan.log

Here is a log with a gb quad, using ATV. There is a PNP DVBT/T2 tuner and I have scanned using the USB tuner. It fails to find the channels using the USB tuner. gb quad atv with pnp_usb scan.log

Same receiver scanning with the PNP tuner finds channels gb quad atv with pnp_pnp scan.log

Same receiver and image. This time without a PNP tuner. Scanning with the USB tuner does not find the channels gb quad atv no pnp_usb scan.log

Using Teamblue, no PNP DVBT/T2 tuner, just the USB one. Scanning does not find any channels either gb quad teamblue no pnp_usb scan.log

@atvcaptain said that it works. So I maybe you have made some changes for Germany's implementation of DVB-T2? @dima73 confirms it is not working in his country as well

AbuBaniaz Recently, new GB drivers have been added to openPli. https://github.com/OpenPLi-meta/meta-gigablue/commit/0d681ce6c3cbbd72a519653910fe8cc5e93c5376 Now you can’t even check anything, enigma2 freezes when you simply open the frontend.

This was on Skype on 09/01/2023. He said he used enigma2-plugin-drivers-dvb-usb-opticombo

OE-A are using 20200723 drivers https://github.com/oe-alliance/oe-alliance-core/commits/5.2/meta-brands/meta-gigablue/recipes-drivers/gigablue-platform-util-gb7252.bb

The 20211026 drivers were reverted https://github.com/oe-alliance/oe-alliance-core/commit/081ecd490a58bcd1d9d8a145398cff186f39e32a

Maybe the platform utilities need updating like here? https://github.com/oe-alliance/oe-alliance-core/commit/011cb2ce6015188a212d3e27eedad91b35098162

update driver * solve the T2 problem * solve dual problem This fixed the issue of dual PNP DVBT/T2 tuner, so far only one tuner(not dual) has been initialized.

Any news on this please?
