In my development system I currently have 4 removable storage
devices...
- 1 USB DVD Device
- 1 IDE DVD Device
- 2 virtual devices (categorized as SCSI and respond very well to my
commands)

I also read the remark you mention about only PnP drivers being able
to respond to IOCTL_STORAGE_QUERY_PROPERTY. However, my worries about
some devices not being able to respond turned out to be unfounded
since running the Microsoft enumcd.exe example showed that all of the
4 devices had no problems whatsoever reporting their adapter
properties.

By the way, I'm currently developing on Windows XP Pro SP2.
