Yes, it sounds plausible. Perhaps I’ll do that. May take some time, I’m a bit busy with other jobs.
CoreELEC consists of a kernel and the rest of the Kodi universe. How complicate is it just changing the kernel? That opens the chance for me to add the older kernel from 9.2.1 to the new releases of CoreELEC. May be a weird idea…
What about my question which DVB-T2 stick would be recommended by the CoreELEC team?
Thank you, CE users where just insist friendly and long enough until this issue was solved. Most hard part on issues like this is that it is not possible for Team CoreELEC to own every piece of hardware available out there on market for debugging.
Just received a WinTV-dualHD today and encountered the same problem with a bit older build of coreelec, running on GT-King Pro. I can confirm that after rebuild from head of coreelec-9.2 branch (9f6f71fbe4) the problem reported in this thread is fixed.
However I get another problem: Hauppauge WinTV-dualHD tuner is not working in any USB 3.0 port of GT-King Pro. It works only in the one USB 2.0 port (marked as OTG) provided by GT-King Pro.
When in usb 3.0 port, following messages are logged:

and it is not possible to show any tv station.
While when running in the usb 2.0 port, it is fine, no error message present and both tuners work simultaneously with tvheadend.
I guess this is probably GT-King Pro specific.
I planned to get a second WinTV-dualHD to be used with GT-King Pro, but that would need to use usb 3.0 ports as only one usb 2.0 port is available.
Any idea how to solve this?
Do you mean it is general problem of USB 3.0 on AMLogic S922X platform, when used together with hauppauge wintv dual?
So tuners like this need to be connected only to USB 2.0, in this case OTG variant?
Hmm, that is not nice.
Still it looks like problem of USB 3.0 of s922x rather than the tuner?
I guess that the -110 error code is -ETIMEDOUT and it comes from usb_start_wait_urb() when timeout expires after call of usb_submit_urb().
It looks like a problem with usb3 transfers, possibly specific to controller used within AMLogic S922X platform.
Or the tuner does not respond for some reason? It would be strange that it would work with usb2 though.
Tested on PC with 5.7.4 kernel, no problem when using usb3 port.
Tested also connected to a usb3 hub (which has been connected to usb3 PC port), no problem either.
When connected that usb3 hub to GT-King Pro usb3 port and then wintv-dual to that usb3 hub, the above described errors appear again. Tried even to use only usb2 cable (instead of the original usb3 cable) to connect the usb3 hub to GT-King Pro usb3 port (i.e. forcing the usb3 hub into usb2 mode), the same errors still.
Basically the AMLogic S922X’s usb3 ports are not usable with the tuner, no matter what you do. But the tuner is usable with ryzen 7 based PC with usb3 ports.
Looks like the usb3 host controller driver issue in my opinion.
– edit –
A bit different errors that sometime appear there:
