I have had complete proven success with this driver on a Hawking hwun2 device and thank you! It works for me on both BT4 and nubuntu with the 2.6.27 kernel all the way from monitor to injection and I can't recall having the channel issues. I am getting a segmentation fault when trying to bring the device out of monitor mode. Any ideas? I am doing some research on my own and if you need more details just let me know.
