I tried to post on the Ubuntu bugzilla, but the response was really slow and I 
gave up there.

The dmesg output you posted there involved using ndiswrapper, thus I did not see 
if the device was able to load the firmware. The specific file for that device 
is /lib/firmware/rtlwifi/rtl8192cufw.bin. It is part of a kernel firmware 
package. I do not know what Ubuntu calls it.
