zunebusenum program is cpu hog!

In loading the Zune software on my computer, I notice a program called zunebusenum.exe that commonly uses 50% of my computers CPU, slowing it down significantly.  Has anyone experienced this issue and/or have any suggestions?  I have heard that this program is for wireless syncing which I don't do with my Zune.  Any hlep or advice would be appreciated.   Thanks!

This is likewise a frequent problem for us.  ZuneBusEnum.exe runs even when Zune is not running and hogs 80-90+% of the CPU.  The entire system drags and printing effectively stops.  We can log into the Admin account and terminate this one process each time, but its getting to bt a major pain in the backside.  We're thinking of dumping the Zune software altogether but we'd rather find a fix that doesn't requre such drastic measures.

Any help?
