connecting USB to wireless port

[Yom]

Hello,

I'm looking for some guidance on the most efficient way to receive signals from a game controller and transmit them out via a wireless interface to a wifi device. The wifi device is actually connected to a microcontroller, so I want to use a simple protocol like UART. The signal from the game controller needs to be transferred as quickly as possible to prevent latency. There will also be signals coming back from the microcontroller via wifi that will be used in a GUI application, but there can be some latency in displaying those signals.

I appreciate any guidance,
Thanks Tom
