Yes, i´m using the Original Micro USB Cable.
I´m starting "Dump Kernel" and then the instrusctions came.
Reconnect, hold reset, power on, hold reset a few seconds..
if i hold it 5 Seconds then release the Reset Button, i get the Error Message: "USB Read Error IOTimedOut"
If i Hold it for less then 5 Seconds, the Power LED Turn on and i get the Error Message: "Can´t write to USB".
I switched the USB Ports, but nothing.
The Driver is ok i think, after installation it says "NES Classic Mini".
MAybe i try to switch the Kernel Dump, but i think this would be "Dumb"
