Initially I was looking for DWA110 where you can also find in many post sharing it works but the goodies are newer model faster speed replacement with DWA125. It equip with Ralink RT3070 chipset. download here and thanks to this post for the update.
After unmount the image file, follow the instructions given for each version of OSx. When done, look for this Ralink Wireless Utility folder in Applications. Fireup the Ralink Wireless Utility for searching (Site Survey) for your signal. Select the right signal name, Connect and Add Profile. Done!
The only small issue was it doesn't show the wireless signal icon on top of the finder, where I think is still ok. Good luck to you.
