Description jorge 2021-01-03 09:14:58 UTC

***Assuming one is building the kernel from scratch***:

following the steps of https://wiki.gentoo.org/wiki/Webcams for enabling uvc webcams in the latest stable kernel (sys-kernel/gentoo-sources-5.4.81-r1) is enough. However, if building with the kernel sys-kernel/gentoo-sources-5.10.4 there are a few extra steps/changes in order to enable webcams, enable:

CONFIG_MEDIA_SUPPORT_FILTER
CONFIG_USB_VIDEO_CLASS (has to be a module, building into kernel doesn't work)
CONFIG_MEDIA_PLATFORM_SUPPORT -> CONFIG_VIDEO_MEM2MEM_DEINTERLACE

(in addition to the previous configurations suggested in the wiki page)

I do not see a bug in gentoo here.
Sounds as a general hint. 
Please improve the wiki as you like.

Please reopen, if you really found a bug.

Hello:

Will do. I'll wait until the kernel is stable and see if something changes. That should also give me the time to do research on wiki best practices.
