[ale] USB Parallel Support

The 2.2.x backport patch does not include support for
the printer cable driver.  It uses the 2.3/2.4 parport
device interface, which is not supported in 2.2.

Quote from http://www.suse.cz/development/usb-backport/:
The patches included here make only minimal changes to the v2.4 USB tree,
to make sure no bugs are introduced by the backport if
possible. This also means that because the parport stuff in
v2.2 and v2.4 is wildly different, that the uss720.c module wasn't
backported and thus isn't included in the backport.
