Just coming back to this problem to explain the situation for Mahmood . . .

The tests you have performed show that the vanilla r8188eu driver
(from upstream, at kernel.org) has been identified and correctly
loaded into the running kernel-ml. In essence, there is no problem
with the kernel-ml package. The problem arises with the way userland
support software that is shipped with RHEL 7 (and, thus, part of
Scientific Linux 7 and CentOS 7) interacts with the driver.

Ideally Realtek should update their r8188eu driver code and submit it
for inclusion in the upstream kernel sources (at kernel.org). Until
that time occurs, modifications to the userland utilities called will
be necessary to use the driver module for your USB dongle.
