Just wondering what is the minimum kernel version to
ignore the device for usb-storage, I am running Ubuntu 12.04
(kernel 3.2.0-24) and it still does not ignore the device.

On the other hand, it is possible to manually detach the
driver using the instruction from Alan Stern.

You can detach and attach drivers by hand.  To unbind hiddev from a
device:

        cd /sys/bus/usb/drivers/hiddev
        ls

Find the filename for the interface you want to unbind.  Interface
filenames have the form

        B-P:C.I

where B is the bus number, P is a string of port numbers separated by
periods, C is the configuration value, and I is the interface number.
Having found the filename for the interface you want to unbind, do

        echo -n interface-filename >unbind

To re-attach the driver, do

        echo -n interface-filename >bind

For the usb-storage, it is similar.
