Well it might be coming down to what adapter you're using. It may have inadequate driver support, but it may also be that you're too far away from the access point (AP), and the broadcast power (PWR) isn't strong enough (higher numbe is better, lower is worse [numbers are negative numbers]), or you have poor receive quality (RXQ - higher number is better, lower is worse), meaning there is interference.
The Alpha cards have built in driver support in Kali, and they're very reliable, so I'd recommend one of them.
Regarding the rausb0 command, I'm not familiar with it. After looking at this
http://www.aircrack-ng.org/doku.php?id=newbie_guide
Does it just display your interface as rausb0 rather than wlan0? As far as finding access points and connected clients, I use and recommend these standard commands.
These will put your wireless interface into monitor mode, and then start monitoring the "air" for traffic from any and all near access points and clients.
aircrack-ng start wlan0
airodump-ng mon0
After you zero in on an AP you wish to monitor, (CTRL+C to stop monitor) you should focus on its channel and BSSID so you can see the RXQ (receive quality) so you can see if there is a lot of interference in the signal. X = variable obviously
airodump-ng -c X --bssid XX:XX:XX:XX:XX:XX mon0
This will show you both the broadcast strength of the XX:XX:XX:XX:XX:XX access point, as well as the RXQ, and it will show any clients (STATION) on that WLAN, and their status, whether associated, or not associated and probing for the AP.
So I'm not entirely sure what your issue is and the purpose of the rausbX command or display you mentioned, but I would suggest picking up an Alpha card if you don't have one, and using these commands to find APs and clients. Let me know if that helps, or if you need further assistance once you've gotten to the point of finding APs and clients and want to continue on towards hacking WEP or WPA2 or WPS.
