The output of lspci is useless for a USB device. Use lsusb instead.

As you found, the 64-bit version of the driver for the device with USB ID
0bda:8176 does not work. The 32-bit one is fine. I did some work on it and found
many of the problems; however, the driver still did not work. When I contacted
Realtek about the issue, I was told that they were working on a mac80211-based
driver that should be available soon. On that news, I stopped work on the old
driver. That was a few months ago, but so far I have not seen any new code. When
they are ready to release it, at least to me, I have an Edimax 7811Un ready for
testing.
