The following tuner layout is working:

A = AVL6211 (DVB-S2)

B = AVL6211 (DVB-S2)

C = Si2169 (DVB-C/T2)

D = TDA18273 (DVB-C/T2)

Combinations of C, D = Si2169 or C, D = TDA18273 result in only tuner C working.

In fmiglius' case, perhaps the following will work:

A = AVL6211 (DVB-S2)

B = Si2169 (DVB-C/T2)

C = TDA18273 (DVB-C/T2)

D = Si2169 (DVB-C/T2)

or

A = AVL6211 (DVB-S2)

B = Si2169 (DVB-C/T2)

C = Si2169 (DVB-C/T2)

D = TDA18273 (DVB-C/T2)

Hello everyone.

First of all, a massive thank you and heartfelt gratitude to the OpenPLi team members for continuously providing the most reliable enigma2 image :-).

In a Vu Duo 4K with one FBC DVB-S2X tuner and one Dual DVB-T2 tuner MTSIF, there was the need to add a dual DVB-T/T2/C USB tuner for multiple simultaneous recordings. After searching on linuxtv.org, it seemed the only one available for sale with good linux support is the Hauppauge WinTV-dualHD. Single USB tuner Hauppauge WinTV-SoloHD is already supported by enigma2-plugin-drivers-ct2-dvb-usb-pctv292e.

OpenPLi team members are absolutely correct in that using USB tuners are asking for trouble but sometimes it is a solution.

On https://github.com/O...penpli-oe-core/ there is a HauppaugeWinTV-dualHD.patch which adds support to the following brands but not to Vu+:

meta-gfutures/recipes-bsp/linux/files
meta-gigablue/recipes-bsp/linux/linux-gigablue-4.4.35
meta-maxytec/recipes-bsp/linux/files
meta-octagon/recipes-linux/linux-octagon-4.4.35
meta-uclan/recipes-linux/linux-uclan-4.4.35
meta-zgemma/recipes-bsp/linux/files

To be able to use it on the Vu receiver, the attached patch was made from scratch and it only includes the kernel commits at the end of this post, some newer than the HauppaugeWinTV-dualHD.patch. The patch was copied to meta-vuplus/recipes-bsp/linux/linux-vuplus-4.1.45/ and added to meta-vuplus/recipes-bsp/linux/linux-vuplus-4.1.45.inc below the line: file://0017-mn88472-finalize-driver.patch \ as file://0018-Add-support-for-dvb-usb-stick-Hauppauge-WinTV-dualHD.patch \.

The compiled driver was tested extensively, even with 4 HD recordings and there are no problems, even when zapping while recording.

Before using the WinTV-dualHD, please make sure it is in bulk mode as on https://www.linuxtv....er_Mode_to_bulk (download https://www.hauppaug...n=FAQ.BulkOrIso and set it to bulk mode).

To install the driver, download and unzip the attached enigma2-plugin-drivers-ct2-dvb-usb-hauppauge-dualhd.zip file, ftp the ipk files to /tmp and run:

opkg install --force-reinstall /tmp/*.ipk

Then reboot the receiver. After it boots, go to tuner configuration to enable the two WinTV-dualHD tuners.

If it is useful to others, I hope OpenPLi would include the patch sometime in the future. Perhaps in a duplicate package of enigma2-plugin-drivers-ct2-dvb-usb-pctv292e, maybe with the name enigma2-plugin-drivers-ct2-dvb-usb-hauppauge-dualhd so that it is a little bit clearer to the end user.

Also, as I am not that familiar with PR and Vu will probably ignore a patch from an unknown contributor, I would be grateful for a kind OpenPLi team member to PR directly to Vu+ so that they can add it to meta-vuplus.

Thank you very much again for all your hard work.
