Subject: [PATCH] Add Digitech USB-Storage to unusual_devs.h (attempt 2)
The mass storage device from Digitech designed for Flash Cards, as found
on (for example) the GNX4 device has issues with residue, similar to the
bug report at http://kerneltrap.org/node/6297. This patch adds the
faulty storage device to unusual_devs.h, this not only reduces the noise
in dmesg but also increases the transfer speeds by a factor of 7x for me
(89kB/s -> 637kB/s).
