Für die Bluetoothgeplagten unter euch:
Wer hin und wieder mal seine Hardware wechselt, hat massenhaft Geräte-Leichen im System.
Ärgerlich ist das vor allem, wenn z.B. die Bluetooth Software als ersten freien Bluetooth COM Port immer wieder COM22 erkennt, weil man vorher ein wenig rumgespielt und das Handy xmal eingerichtet hat.
So kann man über den Gerätemanager nicht angeschlossene Geräte anzeigen und auch deinstallieren lassen:

Ok you have loaded some different Bluetooth software and now the lowest COM port you are getting is in the 10+ range? You've uninstalled and reinstalled until your blue! This is for you then.
There is a difference between hidden and nonpresent devices.
To see nonpresent devices in Device Manager, open a command prompt:
C:\> set DEVMGR_SHOW_NONPRESENT_DEVICES=1
C:\> devmgmt.msc
Then on Device manager click | View | Show hidden" devices | and your nonpresent devices will appear. You can then delete nonpresent devices like your old adapter, or you can delete both instances and XP will reinstall it with a name more to your liking.
To put this environment variable into XP permanently, open SystemControl Panel, Advanced tab, Environment Variables button, System Variables:
DEVMGR_SHOW_NONPRESENT_DEVICES=1
