Issue with xhci-hcd USB-Disk


#1

I am having issues with my self power USB-Disk and could’t find any help so far.
I have pasted the full dmesg here http://ix.io/1wQA

Does somebody have an idea?
I lose the connection to the disk every time the above shown issue happens and have to restart my box to fix it.

The USB interfaces on AML devices are mostly not powerful enough to feed a self powered disk. You need a harddisk with an external power connector.

Thats what I meant. The harddisk is self powered by an external power connector :slight_smile:

Uuh…excuse me, I thought you meant USB powered.
Maybe the problem is, that the USB interface on Amlogic devices don‘t support xhci and the slow down causes connection issues.
But I‘m only guessing here.
