Apocolipse - If you are able to makes heads/tails of this, I'll forever be your hero! The difference here is the the RT2860 chipset from what i can tell is used for the PCIx interface. This is what is built in to the 1000HE. The RT2870 is a USB interface chipset.

This is the link for the driverset. You'll see a 18.104.22.168 version for the RT2860. This one works with the 2.6.29 kernel. They just updated it. However, again, injection does not work. I don't know if you can patch it?
I'll take a look at it, thats half of what I need. Do you have source for a driver that works in BT3 with injection?
