I have a BeagleBoard Rev C5 and I am using Buildroot to make a simple custom Linux system. I'm developing on an Ubuntu 10.04 VM on a Windows 7 host machine. I purchased a Ralink wifi USB dongle and have verified that both Windows 7 and Ubuntu can recognize and use the dongle. When I boot my BeagleBoard after building the system with Buildroot I cannot seem to get the board to recognize the USB wifi dongle, let alone use it.
I have configured Buildroot with udev, wifi-tools, usbutils, usbmount, libusb, and wpa_supplicant. Under 'Hardware Control', I selected linux-firmware and Ralink 30XX driver support.
I've tried to follow these following links as examples but they seem to be focused on using a full-blown distribution like Angstrom or Ubuntu and I want to build a custom kernel with Buildroot:

On Host Machine with USB wifi adapter connected, I get the following outpuf from the lsusb command:
Bus 002 Device 005: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
On my beagleboard I've configured wpa_supplicant.conf to look like below:
phil@beagle: cat wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="NETGEAR"
scan_ssid=0
proto=WPA
key_mgmt=WPA-PSK
psk="PASSWORD"
pairwise=TKIP
group=TKIP
}
If I run lsusb on the target, I get:
unable to initialize libusb: -99
I'm not sure where to go from here. How can I get the BeagleBoard to realize the USB dongle using Buildroot and how can I load those Ralink drivers? Thanks in advance.
EDIT - I've enabled USB controller support in the kernel but still cannot load the driver I enabled for raylink from Device Drivers > Network Device Support > Wireless LAN > Raylink Driver Support from the Linux 3.3 Kernel menuconfig.
Here is what I am seeing when booting the board and trying to get Wifi. Any thoughts on this??

EDIT 2:
If I boot ubuntu on the BeagleBoard the adapter is recognized and by editing wpa_config I can ping www.google.com. I must be missing something in my custom kernel .config or how I am loading the drivers... Any thoughts?

EDIT:
Enable the USB options mentioned below in the 3.2.23 Kernel ( apparently doesn't work in 3.3 ) and enable the drivers I mentioned above and it works!
