USB-Serial-Port Mystery
-
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.
