realtek wifi dongle

[galgavu]

Hi.
I'm new to BSD. I wanted to try it but I couldn't get my wifi adaptor to work. I don't know even a command like in linux 'lsusb' to check what's exactly my wifi dongle is. Can anyone help me with this.
For sure it is realted wifi dongle. What I've done by now is:
added in loader.conf:
if_urtw_load="YES"
wlan_wep_load="YES"
wlan_tkip_load="YES"
wlan_ccmp_load="YES"
wlan_xauth_load="YES"
wlan_acl_load="YES"

and in rc.conf:
ifconfig_ath0="WPA DHCP"

I've also created wpa_supplicant.conf because I use wpa/psk2 on my wifi.
I don't know if any of this I've done correctly. If anyone could help it would be great

Edit: forgot to add, I'm using PCBSD 9.0 beta
Edit2: I checked on linux with lsusb what dongle it is:
Realtek Semiconductor Corp. RTL8188SU 802.11n WLAN Adapter

Is ath0 the correct wifi device name? If so you need something like this
in rc.conf

wlans_ath0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

Then configure /etc/wpa_supplicant.conf with your WPA details.

Use usbconfig as demonstrated here: http://wiki.pcbsd.org/index.php/Wireless_Testing.
