I'm having the same issues. I'm using an Alfa AWUS036H on Kali GNOME 32-bit VM. The aircrack-ng suite works - injection, WEP cracking, capturing WPA handshakes, those are all good.

reaver and wash on the other hand, do not work. It just sits there and no APs are being printed. If I boot into Backtrack 5R3, it works fine. What other information can I provide to help debug this?
