[Dx4win] Anyone using an Icom IC7600 ?

I'm in the process of purchasing an IC7600. I use DX4WIN logging software. If any of you use the 7600, interfaced with your computer for rig control Are there any setup issues? Does the rear panel USB port work OK? I notice that the DX4WIN radio preferences has two options: 7600 250
