Several users have contributed patches to the v56/v57 code tree that
allow the fobbit device driver to compiled on a 2.4.20 kernel system. As
I do not have a 2.4.20 kernel system to test out, nor do the changes
compile on my 2.4.18 kernel box, I am including both.

There are two source files in this directory:
usbvb-2.4.20.c
usbvb.c

Obviously, usbvb-2.4.20.c is the driver for 2.4.20 systems, while
usbvb.c is the one for 2.4.19 and below, I believe. Rename what you
want to use to usbvb.c and build using "make".

Please give me feedback on if this newer module compiles on older kernel
revisions. Else, if someone wants to apply the patches in a more elegant
fashion so they compile on both systems, please do so.
