Retaining COM ports with Norton Ghost

We are ghosting a system that is attached to several USB-to-serial devices. These show up as a virutal COM port in Windows. These devices will retain their COM port when detached and re-attached to the same system. However, when an image is restored the COM ports change. The Windows device driver installation mechanism runs and the devices get assigned the next highest port numbers. We would prefer they stay the same.

 

I realize this is probably a Windows issue and not something you can fix in Ghost. Any known work-arounds?

 

Environment:

Windows 7 Professional

GhostCast Server 11
