Nach nun langer Sucher und Treiber Updates hab ich ein Dead End mit diesem Problem erreicht: 64GB USB 3.2 Stick an USB 3.0 Mainboard überträgt nur mit 20 MB/s. Da selbst eine externe Festplatte mit 80MB/s überträgt und der Stick an einem anderen PC auch auf fast 100MB/s kommt, muss sich das Mainboard wohl nicht mit dem Stick vertragen. Warum weiß ich nicht und ob man dagegen was tun kann. Außerdem wird der USB Stick heiß (zu heiß zum Angreifen, 50-60Grad), auch wenn er nur am Port steckt. Nach Update des ASUS P9X79 Deluxe mainboard welches einen ASMedia USB Chip besitzt, ist der Treiber nun sowohl für ASMedia USB 3.0 eXtensible Host Controller - 0.96 (Microsoft) und USB Root Hub (USB 3.0) und Generic SuperSpeed USB Hub auf Treiber Datum ~2021 unter Windows 10 64bit. USB Tree View zeigt soviele Daten an, kennt sich hier irgendjemand so gut aus, dass er weiß, auf was man achten müsste um eventuelle Problem zu erkennen? Hier sind die Geräte geordnet in der Reihenfolge von USB Tree View (siehe Foto), ich hab keine Ahnung nach was ich Ausschau halten soll um einem Fehler auf die Spur zu kommen. Sieht alles ziemlich gleich aus. ######################################################## ASMedia USB 3.0 eXtensible Host Controller ######################################################## ===================== USB Host Controller ======================= +++++++++++++++++ Device Information ++++++++++++++++++ Friendly Name : ASMedia USB 3.0 eXtensible Host Controller -
