Perhaps it uses USB1 and not 2? Can you rmmod all *hci_ucd modules except for ehci_hcd and see what happens? Did you try cp (or cp --sparse=always if you really want to) and see if it helps? I don't know of a similar option for dd. -- Didi _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
