The literature says the adapter is RWND-N1501UB/RWNDN1502UBE and has support in Linux kernels 2.4 and 2.6, when plugged in, /var/log/messages shows the following:

usbconfig shows the following:

Right now I'm running a generic kernel until I can figure out a driver for this, if one exists. I'm really anxious to get this working as it will save me about $200 (a new hard drive and a copy of Windows 7). Also, I received the adapter as a gift so I'm not out any money on the adapter.
 
That will be a tough one because /usr/src/[Arch]/conf/GENERIC #Wireless NIC does not appear to have a driver for that device. You might wont to try a similar driver http://wireless.kernel.org/en/users/Drivers/rt2800usb#available_devices or maybe it is working and not configured?

I would also try to extract the driver from the .exe (used for windows) by using unrar, unshield, or unzip. One of those will open the .exe and produce a .inf and .sys file you can use.

I found the best thing to do is buy a common wireless driver like Atheros or Intel because cheap ones typically use "new" drivers.
 
For some reason my post is not showing up. #config-network-ndis in the FreeBSD handbook under "Setting up Network Interface Cards" will show you how to extract the driver from the .exe file and use it.
 
It may help others troubleshoot their wireless. Moreover, the suggestions made are not wrong. If NDIS can make use of a Windows driver, that's progress. If native-driver-supported hardware (which is usually not expensive) can be used, that is also progress.
