Dear Mark,
I suspect the above poster has confused OSBDM and USBDM. The drivers are different.
However, I have done some basic tests with a MCF52295 DEMO (OSBDM) and it seems to work fine under Windows 7 professional 64-bit. I'm not sure where the drivers were loaded from as I have several Codewarrior products installed but, obviously, one of 'em did it.
I suggest installing Codewarrior V10 (if not already done) and see if that installs the drivers.
Looking at the hardware manager it appears that the required low-level driver is libusbV0 (64-bit) (from memory, I'm at another computer at the moment.) . You can search for a signed version of this driver on the Web. This link MAY be useful:

Alternatively - contact Freescale direct. I don't believe they monitor this forum (self help perhaps?)
bye
