Terry Polzin on the Fedora list today posted a request for help with getting a Realtek 8188S(U) working. I replied saying that I had a similar device and shared my experiences.
I told him that there is a driver in staging which supports the device, but that Fedora only ships quality working drivers by default, so no staging drivers are included. It's easy enough to get them though, just add the RPMFusion Free repository and install their kmod-staging package which (as the name might give away) includes the staging drivers for the current kernel.
Once you have that installed, the r8192s_usb module can be loaded, but the device still needs external (presumably proprietary) firmware to work. Fortunately, although the driver available from Realtek does not include it, it was included on the disk, and is also available in the Billion driver from their website. So, once you have put the firmware in the right place, the device just works.
Here are the steps to get it working (you will need to have RPMFusion enabled, and run these as root).
yum install kmod-staging unzip
unzip -j 3011N_Linux_Driver.zip "*rtl8192sfw.bin" -d RTL8192SU
The main downside here (apart from the obvious) is that you will be relying on RPMFusion to build an updated kmod-staging version when you get a Fedora kernel update. Sometimes this might not happen before you get your kernel, so when you reboot, you lose your wireless (because there's no driver). If so, boot to your older kernel for a while, or build the driver yourself, or create an akmod instead of kmod.
