I think you can't get a list of usb ports in the pc,just the lists of usb DEVICES connected. Refer http://stackoverflow.com/questions/3331043/get-list-of-connected-usb-devices[^

You can do this using a WMI query on Win32_USBHub.

http://msdn.microsoft.com/en-us/library/aa394506(v=vs.85).aspx[^]

Download the code from here:
http://code.msdn.microsoft.com/windowsdesktop/Using-WMI-with-C-4e5a9ee1[^]

Change the line:

C#

SelectQuery query = new SelectQuery("select * from Win32_Service");

to:

C#

SelectQuery query = new SelectQuery("select * from Win32_USBHub");

AND change:

C#

List<string> serviceNames =
    (from ManagementObject service in services select service["Caption"].ToString()).ToList();

lstServices.DataSource = serviceNames;

to:

C#

List<string> USBNames =
    (from ManagementObject service in services select service["Name"].ToString()).ToList();

lstServices.DataSource = USBNames;
