USB-Massenspeicher werden nicht mehr angezeigt

Guten Abens allerseits,
ich habe seit ein paar Stunden ein eigenartiges Problem.
Es geht um drei Geräte:
Externe Festplatte: Verbatim Modell# 53018 1TB
Zwei mal Speicherstik: HP 8GB

Die Festplatte war an einem Netbook (Windows 7 Start) angeschlossen und funktionierte dort Problemlos. Die Stiks habe ich an ein Windows XP System angeschlossen um Sie dort bootfähig zu machen. nach dem der in folge beschriebene fehler mit dem ersten Stik auftrat versuchte ich den zwoten.
Der Stik wurde angeschlossen und nicht mehr erkannt. In folge auch an meinem anderen PC mehr. Nachdem ich dies feststellte versuchte ich die Festplatte an zu schließen. Auch diese wird nicht mehr erkannt. Ein dritter Stik (Intensio 1GB) wurde erkannt. Mittels LinuxLive USB Creator 2.8.6 bootfähig gemacht und mit Ubuntu 11.10 versehen. All das funktionierte reibungslos, nur die drei erstgenannten Geräte sind nach wie vor defekt. Windows sagt zum Gerätestatus „Für dieses Gerät sind keine Treiber installiert.“ unter Ubuntu 11.10 werden die geräte via lsusb nicht mit angezeigt.

Ich kann mir nicht vorstellen das 3 Geräte innerhab von 30 Minuten an einem nachweislich Funktionierendem USB Anschluss zu Grunde gehen, der im anschluss weiterhin problemlos genutzt werden kann.
Das Tool „USB Fehlerbehebung“ ist wirkungslos.

Über eine Idee zum weiteren vorgehen wäre ich dankbar.

Liebe Grüße,
Christian
