Hi All, I am using "USB to serial port converter" to program my USB port.As soon as the USB cable is plugged-in the driver installed allocates a COM port number to the USB Port. So usually the last allocated port number is for USB.In my program when the user opts for communiocation over USB port i will find all the valid ports in the pc and assume the last port number as the USB port number.If the USB cable is not connected then no COM Port number is allocated to USB port.So the method i am using to find out the COM port number allocatted USB port is not robust method. So i just want to know whether there is any method to find out the USB cable connected to the USB port through VB code.. Somebody help me with this. Thanx in Advance, Sushma
