Reaver uses the standard libpcap library to open the monitor mode interface, so 
if libpcap can't open it there isn't really any code changes that I can make to 
fix this AFAIK.

Your driver is the r8187, not the rtl8187. This is probably because you are 
using an old version of backtrack. Download BT5 and things should work better 
for you.

I can reporoduce this in Backtrack R5.1. Using svn rev #90 and issuing ./wash 
-i mon0

Edit: Same USB WiFi interface as op.

I also got this on Backtrack R5.1 .. however after doing 

airmon-ng start wlan0 

it started working!
