When working with USB Serial Adapters or other devices that appear as USB Virtual Serial Ports, it's not unusual to end up with a large number of COM ports that are listed as "In Use".

This tutorial shows how to delete these old entries.

(The tutorial is in a pdf file. You need to be logged in to download it.)

js,

For Windows XP, just use the same procedure except:

    Log in as Administrator. Open the Command Prompt window the normal way (not right click).
    Follow the steps as shown in the pdf.
Remember that you must open the Device Manager from the Command Prompt window.
