Serial Port Assignment

[Guest]

I have, over time, installed many USB serial devices on my machine. I did not
properly remove these devices, and no longer have access to some of them. Now
when I plug in a new device it gets assigned COM14 (etc). Is there any way to
re-set the comm port database so lower ports will be assigned?

To display hidden devices, non-Plug and Play devices, and devices not
attached to the computer (commonly known as "ghosted" or "phantom" devices)

Save the following two lines as a file then execute.

--------------------------setdev.bat---------------------
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc
---------------------------------------------------------

Then, View|Show Hidden Devices to remove or reconfigure these devices. Do
not edit the registry.

I have tried that, and removed a couple of entries, but still there are more
that are not listed, and the assigned port for a new device is too high. Any
other ideas?
