Just a heads-up to any non-Windows users...
VirtualBox:
The Prime Connectivity Kit and Prime Emulator both work as expected in Windows XP running in VirtualBox. I can communicate with both the real and emulated Primes this way.
WINE:
The Prime Connectivity Kit and Prime Emulator both run under WINE... but you cannot communicate with a physical Prime via usb. You can however communicate between the emulated Prime and the Kit.
All the above tested in a rhel 6.4 clone.
