You missed some important steps we've already written, man.

First try this, then we'll see what about 'rtl8192su.ko & Co.'
Don't break lines.

1. Check whether you have installed the necessary firmware

$ rpm -qf /usr/lib/firmware/rtlwifi/rtl8712u.bin
linux-firmware-20141013-41.git0e5f6377.fc20.noarch

~~~~~~~~~~~~~~~~~~~~~~~~~~

2. Create udev rules file

/etc/udev/rules.d/70-modprobe-r8712u-for-FR-300USB-WiFi.rules
#
# 07d1:3304 D-Link System FR-300USB 802.11bgn Wireless Adapter
# Load the module for unsupported device after creating devices
#
SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="07d1", ATTRS{idProduct}=="3304", RUN+="/sbin/modprobe -v r8712u"
#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3. Create service unit configuration file

/etc/systemd/system/FR-300USB-WiFi-ID-to-r8712u.service
[Unit]
Description=Append FR-300USB WiFi ID to rtl871x wireless lan driver

[Service]
ExecStart=/bin/sh -c '/bin/echo 0bda 8171 > /sys/bus/usb/drivers/r8712u/new_id'

[Install]
WantedBy=multi-user.target 

~~~~~~~~~~~~~~~~~

What's the score?

$ cat /sys/bus/usb/drivers/r8712u/new_id
$ dmesg | grep r8712u
