32 bit VM on 64 bit OS?

I've found one reference so far to anyone suggesting running Calibre in a 32 bit VM on a 64 bit OS, but no actual reports of anyone trying it.

So, I thought I'd give it a try. I'm running Windows 7 64 bit (Beta) with Windows XP 32 bit running in a Sun xVM VirtualBox.

Calibre installs, but it get the following unhandled exception error:

[Error 13]The data is invalid

Detailed traceback:

Traceback {most recent call last}:
File "calibre\gui2\device.pyo", line 29 in run
File "calibre\devices\scanner.pyo", line 40, in scan
WindowsError: [Error 13] The data is invalid

I installed the USB driver during install. I searched the forums to see if maybe these errors were directly related to not having the proper USB driver, but found they tend to be more general in nature.

I suspect they may be associated with no USB driver as I would imagine that the hardware abstraction offered by VirtualBox may not be sufficient to allow the 32 bit USB driver to load.
