[SOLVED] Kernel 6.3.0 mouse & keyboard not working

I have a USB mouse and keyboard. When I boot kernel 6.3.0 X boots normally but neither mouse nor keyboard function. When I boot the prior kernel, 6.2.12, both work normally.

Here is Xorg.log for kernel 6.2.12.
Here is Xorg.log for kernel 6.3.0.

Any debugging hints will be gratefully received.

[SOLVED] Many thanks to CaptainBlood (below) for so clearly pointing out the error I made in the .config for building kernel 6.3.0. [/SOLVED]

That setting was added in HID: Kconfig: split HID support and hid-core compilation, which made it default y to minimize compatibility problems. According to the logs, it was meant to be included in v6.2, but was deferred to v6.3.

had the same problem, this fixed it. Thanks!

(I kinda feel like the object description should have more urgent warnings about how not saying Y here will result in no mouse/keyboard. I'm sure I'm not the only desktop user who routinely says N to new features unless they look really important).

Also, another important note: for whatever reason, the specific kernel module for my trackball (which seems only to have been added to the kernel a year or two ago) wasn't enabled, but the 6.2.* and previous kernels nevertheless registered it. Now, with the 6.3 kernel, the extra Fn buttons on the mouse don't register unless I specifically enable the kernel module. I'm not sure why this turned out this way, but I was unable to use those buttons until I had the module activated.
