Have been browsing my notes and found this which shows I might be wrong and at least we have the driver which is a good start
Your 8192cu USB wireless chip should work with
wireless-3.0.21-tinycore.tcz which contains the rtl8192cu.ko driver you're looking for.
All you need now is the firmware. I have the older version and will submit it soon. So look for
this extension firmware-rtl8192u.tcz later
Alternatively you may try the extension firmware-rtlwifi.tcz which is in the tc-5.x repo, this has the latest firmware (rtl8192cufw.bin) for your wireless chip AIUI
Pleas let us know if
wireless-3.0.21-tinycore.tcz
and
firmware-rtlwifi.tcz
work for you
if the new firmware is not compatible, I'll make the older firmware version and submit it asap
