WinTV-Nova-S2 USB revision BAH9 (PCTV_461E) support, work around and fix
Just repeating the issue raised here: https://github.com/b-rad-NDi/media_tree/issues/12
I created a /etc/modprobe.d/dvb.conf with the contents:
options em28xx card=92
Ran a depmod -a and rebooted.

And all the usual apps (like tvheadend) work perfectly.
As I have a DVB-T2 quad tuner with the same em28xx driver being used - overriding the card means only one can work at a time - so the best fix would be in the driver so card 92 is used instead of card 104.
I'm creating an issue in this repo as it looks like issues here are more noticed, and perhaps help others with a similar issue.
Sadly the media_build backports for linuxtv.org which this repo depends on is no longer supported: https://git.linuxtv.org/media_build.git/tree/README so it can only be a patch in the main kernel repo and installed (at least with Ubuntu) with their newest mainline kernel builds to install the version which would incorporate a fix.
Some additional info - cards 92 and 104 are in: https://github.com/torvalds/linux/blob/master/drivers/media/usb/em28xx/em28xx.h#L131
#define EM28178_BOARD_PCTV_461E 92
#define EM28178_BOARD_PCTV_461E_V2 104
So it seems the newer USB devices are being mis-identified as V2.
Did some more digging and this was introduced into the kernel by @b-rad-NDi when adding 461e v2 support: https://github.com/torvalds/linux/commit/985b0edefa3146a59005832c2b271f9290635b31
I think the fix would simply to change https://github.com/torvalds/linux/blob/master/drivers/media/usb/em28xx/em28xx-cards.c#L2778-L2779
From:
{ USB_DEVICE(0x2013, 0x0461),
.driver_info = EM28178_BOARD_PCTV_461E_V2 },
To:
{ USB_DEVICE(0x2013, 0x0461),
.driver_info = EM28178_BOARD_PCTV_461E },
Assuming the usb id of 2013:0461 is universally a e461 and not a e461 v2 device.
Confirmed this worked - I re-built the Ubuntu 6.5.0-1006-oem kernel packages for 22.04 with the above patch, and also changed the MAX_DVB_TUNERS to 32.
Now have 2 x WinTV-quadHD DVB-T2 PCIe cards (with em28xx driver) and a WinTV-NOVA-S2 (Rev: BAH9) with the em28xx driver all working at the same time:

Bus 001 Device 012: ID 2013:0461 PCTV Systems PCTV 461
Reception on all devices is excellent.
Additionally: secure boot certificates worked so left secure boot enabled, and since zfs if included in the Ubuntu kernel this all works without needing to use the zfs-dkms package.
Here's the diff and roughly how I built it:

Hello!
I have tried the workaround by setting "options em28xx card=92" and the card changes to "461e" without v2, but the card isnt available anymore in tvheadend. Do you have any hint?
