Has anyone had success using a wireless dongle on the rPi with Controla?

I've tested my rPi with a single Gridseed, directly connected to my router, and it seems to hash successfully. Although, the Controla web page is really not accessible while the Gridseed is hashing (I can see the results from the pool side however).

If I try this very same setup, but with a wireless dongle instead, Controla doesn't even recognize that there is a Gridseed attached.

I'm thinking that maybe the wireless dongle is overloading the USB interface on the rPi, but I'm pretty new to the rPi. I did try the same test with a Scripta image and had the same results basically.

This is the wireless dongle that I have been testing: http://www.amazon.com/dp/B00FADTN14/ref=pe_385040_30332190_TE_M3T1_ST1_dp_2
