The results are in general a lot more promising (apart from the first line) - plus I was able to read/write files without problems: > > Dec 08 15:47:48 charon kernel: usb usb2-port6: config error > Dec 08 15:47:49 charon kernel: usb 1-6: new high-speed USB device number 4 using xhci_hcd This is puzzling. The device connected at SuperSpeed in the previous tests. Clearly this is related to the warning in the preceding line (the port failed to configure its link partner). What could have happened? A problem in the cable? The usb-storage quirk setting would not have affected this. Alan Stern
