IDE Programmer Setting for Esplora: AVRISP mkII or USBasp?

What is the correct setting for Programmer (Tools -> Programmer) in the IDE (version 1.0.5) when working with the Esplora? The default is AVRISP mkII but posts in the Forum recommend USBasp.

What programmer are you connecting to the board? Atmel AVR ISP MKii or something else? Arduino as Bootload programmer:

CrossRoads - Thanks for the reply. My question is more basic: I can't communicate with my new Esplora board and, having manually configured the USB ports, I am trying various settings. Is the Tool -> Programmer setting relevant?

Tool -> Programmer is only relevant for: Tools:Burn Bootloader and File:Upload Using Programmer (overwrites bootloader with your sketch)
