QuestionC#, Win'7, Port Mystery Pin

Today the ports were getting confused and Win'7 was lying to me again.

I first removed the device (Control panel ---> Devices and Printers ---> removed the external device which was connected by BlueTooth.)

I then went to device manager, and deleted all the ports that I knew were bogus.

I then went back to Devices and Printers

I added the known device.

Windows reported that COM20 was back on the list.

There were a total of 4 Com Ports

COM1
COM2
COM18
COM20

Within a few minutes, I watched, king of the clueless, as Windows started adding more Com ports, specifically,

COM25
COM28
COM29
COM30

Following this, Win'7 begins lying to me again, telling me that I have two COM20 ports.

This was exactly and precisely the same problem I had which kept me chasing clouds for 10 days, and I do not want to repeat the previous behavior.

There are a total of 4 USB devices connected to this machine

One USB Hub with three devices attached
-- A debugging device for the embedded system
-- An external hard drive
-- The bluetooth device

There is one other USB cable connected to thin air

What on earth is going on ?

Why is Win'7 reporting two COM20 ports ?

I welcome and thank anyone who can provide any answer behind all this.
