Maybe this helps some folks with the same issue: On copying larger files, my system syslog showed multiple times usb 9-2.4: reset SuperSpeed USB device number 4 using xhci_hcd
As root the following command line fixed the issue with the usb storage driver modprobe -v usb-storage quirks=0x174c:0x1053:u If that works you can persist it by entering this into rc.local or similar. hth, ew0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208993 Title: Ubuntu slows down and hangs while copying file from/to USB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1208993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
