Hallo,
danke für die vielen Antworten und tollen Infos.
Die Diode ist unschuldig. Habe sie rausgelötet und es kommt immer noch im Gerätemanager "Unbekanntes USB-Gerät (Fehler beim Anfordern einer Gerätebeschreibung). Unter Details kommt bei den IDs Device Descriptor Failure.
Es ist ein PL2303GL, wenn mich meine Augen nicht täuschen. Leider finde ich kein ausführliches Datenblatt, oder stelle mich doof an.
Treiber habe ich verschiedene getestet. Auch ältere unter Win 10 und Win 11.
Hier die Ausgabe von USB Device Tree Viewer:
