Can not install more than 4 x Hauppauge WinTV-QuadHD-DVB in a system
Hello,
As per title, I've been struggling to use 5 x Hauppauge WinTV-QuadHD-DVB in a single system without any success.
It seems that the driver will correctly identify 4 of the cards, but the fifth one will fail. These

Please note that I DID NOT pass the card=2 option, this is somehow automatically inserted.
I have attempted to use pass card=56,56,56,56,56,56,56,56,56,56, but the kernel will complain with:
cx23885: `56' invalid for parameter `card'
card: can only take 8 arguments
The devices all seem identical, as per lspci:

The last device will seem to fail due to a firmware error, which I have installed, but I'm assuming this is just because the card detection fails, and obviously it will reject the firmware:

After a rmmod cx23885, I have tried manually loading the module with:
modprobe cx23885 disable_analog_audio=1 disable_analog_video=1 dma_reset_workaround=2
which will fail with:

See full log of module: cx23885.log
Again, trying to manually load with the cards option produces an error:

As an aside, I have the same problem on non-HWE (the 5.4.x kernels).
I have also tried the latest Ubuntu HWE 20.04 kernel (5.15.x branch), with the latest media_build tree and I'm met with similar issues, although not so verbose, but clearly an indexing issue:

Please advise.
I'll post the resolution, as I've finally figured out what's going on.
The cx23885 defines a maximum number of 8 devices, for some... reasons:
#define CX23885_MAXBOARDS 8
Changing this value to 16 technically fixes the driver issue. You can now pass up to 16 parameters to card=, or just let the module autodetect, as it will do a good job by itself.
Next thing you'll find out is that the default Ubuntu kernel defines a CONFIG_DVB_MAX_ADAPTERS = 8, for, again, some obscure reasons.
The author of this PPA, @b-rad-NDi patches the setting itself to 16, as per this comment: https://github.com/b-rad-NDi/Ubuntu-media-tree-kernel-builder/issues/40#issuecomment-371512505
I attempted to use the script in this repository to plug in my own changes and make the all the debs in the PPA, but I was highly unsuccessful - there are no instructions, and I couldn't figure out the correct procedure/order of the operations.
In the end, I managed to re-compile the debs posted, by downloading the source debs of this project and following the re-build instructions after making my changes.
I've followed this old article: https://raphaelhertzog.com/2010/12/15/howto-to-rebuild-debian-packages/
