Das es sich um eine andere Hardwarerevisionen handelt, würde es am ehesten erklären. Ein Foto des Sticks anbei. Zum Einsatz kommen die Standard Ubuntu-Kernel.
Die Firmware aus deinem Link passt von der Version 6.0.1 zur Firmware des Sticks. Ich hatte sie zunächst auf Grund der Dateigröße ignoriert. Dann habe ich noch 2 weitere Quellen gefunden, die unterschiedliche Größe haben, sich aber beide mit Version 6.0.2 melden. Leider funktioniert keine von denen:
