I would like to develop a virtual cd drive by using only UMDF.
Is it possible? or impossible by any restriction of UMDF?

I've been trying to develop it based on VirtualSerial sample UMDF driver in
the WDK.
On Windows XP it is successfully installed but doesn't act as CD-ROM drive.
On Windows 7 seems success to install but then loading device driver failed.

What should I implement add to VitualSerial?

Any help would be much appreciated.

Currently UMDF doesn't support writing virtual CDROM drivers.

Thank you for your reply.
I will try it with kernel mode.
