[CentOS] Configure wireless USB ethernet

[Ashley M. Kirchner]

Ok, got it installed and I can get the interface to scan and I can see all
of the available cells (all of my neighbors), including my own.  However
when I do a test connect, this is what I get back:

Trying to associate with e0:46:9a:35:fb:98 (SSID='Nymphadora' freq=2412 MHz)
ioctl[SIOCSIWFREQ]: Device or resource busy
Association request to the driver failed
Associated with 00:00:00:00:00:00
CTRL-EVENT-DISCONNECTED bssid=e0:46:9a:35:fb:98 reason=0

Over and over and over again.

Please note, NetworkManager is still running.  If I stop NM, that interface
disappears and an attempt to scan tells me:

> iwlist wlan0 scan
wlan0     Interface doesn't support scanning : Network is down

So evidently, I need NM running for the interface to be present.  How can I
do that without NM?
