I have to admit that I had quite some problems in finding the firmware
image for rtl8192su/ r8192s_usb as well, but just tried the version you
commited to
svn://svn.debian.org/kernel/dists/trunk/firmware-nonfree/ in r15379
first - and found it to be working reliably with 6.5 MB/s (distance:
2 metres, little interference, wget(r8192s_usb) <--> Atheros AR9100 MAC/BB
Rev:0 AR2133 RF Rev:a2, ath9k, ath9k_rate_control <--> GBit/s ethernet <-->
vsftpd(RTL8168d/8111d) from a local server).
Looking at the RealTek server, I find this firmware image inside the RTL8192SE driver
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#2302
which currently resolves to rtl8192se_linux_2.6.0015.0127.2010.tar.gz
972eca3225a018e949a097ad7b91567f *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/Realtek-Firmware-License.txt
70ff412e813567ee331ce5edf05f4ddc *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/rtl8192sfw492.bin
a65de7d458c00adbe96893341a3ff151 *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/rtl8192sfw74.bin
a5ad703551efb108ba012b4b8a830d93 *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/rtl8192sfw.bin
and I've been operating my RTL8188S successfully with rtl8192su/ r8192s_usb
a5ad703551efb108ba012b4b8a830d93 */lib/firmware/RTL8192SU/rtl8192sfw.bin
Searching for the term 'rtl8192sfw.bin' certainly suggests different
results as well, the most prominent having a md5sum of
68533bf8078a9e00966a78c9f2da4b9b, which seems to originate from a driver
version called rtl8192su_linux_2.6.0002.0708.2009, however I haven't found
any legitimate source (nor copyright info for the supplied firmware images)
for this tarball yet - while I didn't test that version, a clarification
about the preferred firmware for rtl8192su/ r8192s_usb would be very
appreciated.
Regarding the firmware-nonfree/ firmware-realtek Debian package, it seems
to be safe to add
a5ad703551efb108ba012b4b8a830d93 *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/rtl8192sfw.bin
as known working (at least for me) origin for
a5ad703551efb108ba012b4b8a830d93 */lib/firmware/RTL8192SU/rtl8192sfw.bin
given that
972eca3225a018e949a097ad7b91567f *rtl8192se_linux_2.6.0015.0127.2010/firmware/RTL8192SE/Realtek-Firmware-License.txt
is (sans whitespace changes) identical to
http://svn.debian.org/wsvn/kernel/dists/trunk/firmware-nonfree/realtek/LICENSE
