Running JRK software on a Mac

I installing the JRK drivers on a Mac running in PC mode at the same time using the latest Parallels but I could not get the USB driver to work right. It seemed to install OK but when I connected the board, it came up as unrecognied USB device. FYI I have Mac OS 10.6.1 and Windows XP SP3.

Has anyone with a Mac gotten this to work?
