Wireless usb adapter connect to s3 or enable monitor mode in s3

Dear members,

I have a s3 with backtrack 5 and I wan't to use a monitor mode antenna in backtrack 5. So I have two choices:

-enable monitor mode on the s3 wifi antenna (there is a blog and some subjects in xda forums) : I have to install a driver ...

-connect a wifi usb adapter to s3
I've tried to connect one with OTG usb host it didnt recognize it : I have to install a driver...

Can someone just build for me a ko file to insmod in my rooted s3 kernel 3.0.15?

These are some infos about my phone:
