Hornettek Usb Wireless Driver

I am trying to figure how to install this WLAN USB antenna and it is giving me some trouble, any help appreciated.
The chipset used is Realtek RTL8192su for which I loaded the driver using ndiswrapper.
After installing the driver I can finally see the LEDs working and suprisingly I can scan for networks using this device:
A good indication that the device is somehow working.
Now the problem is that in Network Manager the device always appears as Disabled. If i turn the laptop wireless ON I can see all available networks. When I turn laptop wireless off and plug the antenna I get the above iwlist scan but, in gnome GUI, the device appears disabled.
It is worth mentioning the driver (net8192su) does not appear in lsmod
Any ideas?

High-powered external Wi-Fi adapters such as the Janus WLAN USB adapter can greatly extend the reach of your wireless network – HornetTek claims a range of up to 1,000 meters.

It maintains a strong wireless signal in taxing conditions too. Connecting to your Mac via USB, setup isn't helped by a complete lack of Mac instructions and a software CD that hides the OS X version of its WLAN management app in a folder marked 'Other drivers'.

If you've set up wireless networks before, getting it up and running shouldn't be too problematic, but beginners should wait until HornetTek publishes a decent tutorial.

The device sits neatly on your desk, but could use a bracket to mount it on your MacBook's lid.

In our tests, Janus did exceedingly well, outperforming its rival USB highpower wireless adapter Wi-Fire. With our router in a thick-walled Victorian house, it achieved a 95% signal strength from the garden shed, while Wi-Fire managed less than 20% and AirPort failed to connect at all.

It regularly found substantially more networks, and in our Ping test, was 44.8% faster than AirPort and 36.8% speedier than Wi-Fire.

HornetTek Janus High Power 802.11 b/g/n WLAN USB Adapter is ideal for situations where you struggle to get a wireless connection. Just make sure you know how to set it up before you buy.
