USB Shield Host

I have a SparkFun Redbot Inventor's Kit and I want to make it bluetooth controllable. I have a USB bluetooth dongle, but the mainboard only has a mini USB B port. So which USB shield host should I buy? The board I have is atmega328p and the hosts I found are all compatible with Arduino Uno 328. Is that the same thing?

This is very important, so a quick answer would be super helpful. Thanks!

There is nothing quick about USB hosting. It is a big pain. Cut your losses and get a serial BT adapter.
