I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.
When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

I am developing a UI for an embedded device that I have designed and built. The device uses an FT232 chip which, when connected via USB is automatically assigned one of the COM ports. I was wondering if there is a way to set up a loop which would automatically detect which COM port the device has been assigned. I could then add some handshaking to verify that the port is correct.
