SYMPTOMS
When you start a virtual machine on a Macintosh computer that has a USB serial adapter in place, you receive the following error message:

&quot;The PC name couldn't use the Mac serial port associated with COM #. The port is likely in use by another PC or another application.&quot;



CAUSE
In Mac OS X, you must configure the USB-based serial port in Virtual PC settings, and then restart the computer. If you view the settings again after you restart the computer, Virtual PC incorrectly indicates that the port is in use.



STATUS
This problem was corrected in Virtual PC version 5.0.2 for Mac OS X.
