device descriptor read/64, error -71

Hello everybody,

I tried to mount my USB BAR / USB memory stick but dmesg (or tail -f /var/log/message) told me

device descriptor read/64, error -71

I could solve this by issuing the following command:
echo N > /sys/module/usbcore/parameters/old_scheme_first

If you unplug the USB Memory and plug it in again you should be able to mount it via
mkdir /mnt/sda1
mount /dev/sda1 /mnt/sda1

If you want to start the usbcore.ko each time with the old_scheme_first parameter create a rc.local file for debian system by doing the following:

Make a file /etc/init.d/local with the following lines:
#! /bin/sh
echo N > /sys/module/usbcore/parameters/old_scheme_first
mount /dev/sda1 /mnt/sda1

Save the file and make it executable by typing in the console
chmod +x /etc/init.d/local

The last command you need to type is:
update-rc.d /etc/init.d/local defaults 80

Kind regards
