I've been trying to get the Polar Infrared USB adapter to work so I can upload data from my Polar s625x Heart Rate Monitor (I have Parallels 3.0 and Mac OS X 10.4.10). When I plug in the IR device, Parallels gives the "Parallels USB device you are trying to connect to the virtual machine is being used by another application..." error. I found one page on the web that suggests how to make it work: http://www.amazon.com/Polar-S720i-Heart-Monitor-Watch/dp/customer-reviews/B00018MSN8 However, the crucial part of this suggestion is that I need to "Tell Parallels to share the IR/USB device", which I cannot figure out how to do; in the configuration utility, it is possible to share only folders and applications, but not devices. How do I share the USB device?
