well, .config contains

so the driver is built.

and dmesg contains

so the device is recognised (at USB level).

The module 'rtl8192cu.ko' isn't loaded as expected, however.

Perhaps it wasn't installed correctly - the USB id should have an entry  
in /lib/modules/3.16.7-21/modules.alias of the form 'alias  
usb:v0B05p17BAd*dc*dsc*dp*ic*isc*ip*in* rtl8192cu'
('grep usb:v0B05p17BA /lib/modules/*/modules.alias' should show it)

If the entry is missing, it must appear after the alias file is  
regenerated (with 'depmod -a').

If it's there, but the module is still not loaded when you plug the  
device, please try to load it manually (with 'modprobe -v rtl8192cu  
debug=5') and check dmesg again.

Cheers
Anders
