This is a known bug see:

https://bugs.archlinux.org/task/65368

By patching ch341.c in the gentoo-sources-5.5.5 the problem is resolved see:

https://www.spinics.net/lists/linux-usb/msg190759.html

See my next post for a patch of the gentoo-sources

Patch for gentoo-sources-5.5.5 to get Arduino working again

Place the patch in
/etc/portage/patches/sys-kernel/gentoo-sources-5.5.5/ch341.patch

and re-emerge gentoo-sources, compile and install the kernel.
Then you can upload sketches to the arduino-uno again
