These -71 errors typically indicate a hardware-level problem, either with the USB cables (possibly a cable inside the computer case, connecting the external port to the motherboard) or else a slight hardware incompatibility between the device, the cable, and the computer's USB controller. > 2) Am I missing something in my kernel config (see below) that could be an > issue? No. > 3) If it does appear to be a vendor issue, what should I tell them? Try using different cables and a different computer before deciding the device is at fault. I have an interesting situation involving a USB IDE drive enclosure. It doesn't work at all with one of my computers. If I use a different USB cable then it works. If I replace the IDE drive enclosure with a flash USB device (but keep the original cable) then it works. If I take both the drive enclosure and cable and plug them into a different computer, then it works. So which component is faulty?
