So looks like you found the solution in the other forum, btw:

the driver you need seems an "out of tree" propertary driver. What does it mean ?
It means that is not compiled with the kernel itself, nor built-in [*] or as a loadable module [M], it is simply not in the upstream (or upstream distro patched) kernel.

So you probably had it already in the rootfs the propertary driver "driver.ko" but what is the fact: drivers out of tree compiled against a different kernel version will not be loaded from the new kernel (modprobe complains).

So you need to have re-installed an AUR package, that should be 8192eu-dkms.

I did this, tried to reinstall the package again but it was not working, but after updating kernel it starts to work again

well, so only way i know for such issues is inspect dmesg, and especially /var/log/xorg stuff so to understand what was wrong.
