 2012, Tod E. Kurt, http://todbot.com/blog/
 
 
+A list of Windows-only tools (for now) for inspecting USB devices & serial ports
+
+- usbSearch.vbs    - search USB bus by VID / PID
+- usbSearch.c      - search USB bus by VID / PID (but in C, not VBScript)
+- listComPorts.vbs - list all known COM ports, with other useful info
+
+The .vbs files are executed on the command-line with the "cscript.exe" command.
+For instance, to list all the COM ports, run:
+
+$ cscript.exe //nologo listComPorts.vbs 
+COM26 - FTDI - FTDIBUS\VID_0403+PID_6001+A6004CCFA\0000
+COM24 - PJRC.COM, LLC. - USB\VID_16C0&PID_0483\12345
+
+The above example shows an Arduino Diecimila and Teensy plugged in.
