Oh yes. So end most of my merry bug hunts. :)) (Please sign the Thomas-is-not-to-blame warrant and file it to the applicable authorities.) Now how do i identify whether my BD burners are at USB 3.0 ? The USB boxes are off when booting. I enforce reproducible device addresses by switching them on one by one later. Then i get messages like: [ 9048.631388] usb 1-1.1: new high-speed USB device number 7 using ehci-pci [ 9083.417859] usb 1-1.2: new high-speed USB device number 8 using ehci-pci [10155.914226] usb 1-1.3: new high-speed USB device number 9 using ehci-pci But i also isuccessfully copied about 350 GB from a USB disk: [16375.104439] usb 3-1: new high-speed USB device number 2 using xhci_hcd It seems there is a hardware component involved, which i am glad to not have bought with my new machine. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
