Hey, I went through a similiar problem with my nexus 6. Not to insult your intelligence, but have you tried a different cable? Kali definitely comes with the drivers to run those cards, I know the 722N uses the ath_9k or something similiar, which you should be able to find in your system. I would ignore the people telling you to download the files. What method for install did you use? Does running iwconfig and ifconfig show your card?
