Some piece of software or some driver appears to be using the serial ports COM3-COM49.
New COM ports for Bluetooth et al get assigned ridiculous numbers over 50. When I try to change the number, Windows claim that the lower COM port number is in use, and suggest that I don't apply new settings. However, ActiveSync docs say that COM port number must be 20 or lower.
I have no idea where to look to figure out what's reserving the all those COM port numbers. What other ways do I have for uninstalling devices that don't appear in device manager? How do I figure out what took over those COM port IDs?
Thanks! Here's the MSDN link (also works for Windows 7) http://support.microsoft.com/kb/315539
