Thank you,
I tried to apply this patch to 6.12.39, the first problematic kernel, as well as 6.12.41, the first bad I tried, and on both I got an error message:
Applying: HID: quirks: Add device descriptor for 4c4a:4155 error: patch failed: drivers/hid/hid-quirks.c:1068 error: drivers/hid/hid-quirks.c: patch does not apply Patch failed at 0001 HID: quirks: Add device descriptor for 4c4a:4155
To which kernel version should I apply the patch?
I used the command git am < <file>
Best regards,
Staffan

based on the information in the device descriptor to avoid affecting your device,
You can try this patch and look forward to your reply.

Hi Zhang, hi Jiri,
In Debian Staffan Melin reported that after an update containing the commit 1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY"), the input device with same idVendor and idProduct, the Jieli Technology USB Composite Device, does not get recognized anymore.
The full Debian report is at: https://bugs.debian.org/1114557
The issue is not specific to the 6.12.y series and confirmed in 6.16.3 as well.
Staffan Melin did bisect the kernels between 6.12.38 (which was still working) and 6.1.41 (which was not), confirming by bisection that the offending commit is
1a8953f4f774 ("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY")
#regzbot introduced: 1a8953f4f774 #regzbot monitor: https://bugs.debian.org/1114557
So it looks that the quirk applied is unfortunately affecting negatively as well Staffan Melin case.
Can you have a look?
Regards, Salvatore
