The driver is under development. You can find the source here and in the drivers/staging in the Linux kernel.
If you enabled the rpmfusion repository, you can install the
kmod-staging package which contains the compiled driver.
However, it is reported there are still problems. Such as https://github.com/lwfinger/rtl8188eu/issues/26 .
Keep an eye on the progress in the Linux kernel or you need to try to debug it on your platform.
