I certainly have a device supported by rtl8192su/ r8192s_usb that works 
well with:
	a5ad703551efb108ba012b4b8a830d93  /lib/firmware/RTL8192SU/rtl8192sfw.bin

Therefore it would be very interesting to find out what exactly the kernel/
module says when loading rtl8192sfw.bin and which exact device you're using
(the model doesn't really tell anything), for me it is:

[ 7274.035016] usb 1-3: new high speed USB device using ehci_hcd and address 5

...and it certainly works well (your output will be a lot more verbose, as 
I'm preparing/ using some patches to tune down the excessive function 
tracing).

Here starts the big problem, where does RealTek offer that firmware (and 
not random 3rd parties) and where the license for that firmware images?
When I looked for a matching firmware (what led me to #579694), I couldn't
find rtl8192su_linux_2.6.0002.0708.2009.tar.gz from any official source, 
and those obtainable from shady sources didn't include any license for the 
firmware.
