I want to load a image from an external usb hdd. But each time I try this I got the error message: "usb device not accepting new address 2 (error=-71)" "usb device not accepting new address 3 (error=-71)" I tried the tip with the "F11" key and the command "acpi=off noapic", but the problem wasn't solved; there was the same error! I tried it on another PC without any problem (mainboard Asus P4P800SE)?! The boot cd was made with (german) True Image 7 v638 and the mainboard is an Asus P4B533 and an external case (Mapower MAP-HD31U2G with an Seagate 6,5Gb hard drive with one NTFS-partition). What can I do?
