Sam,
Can you reproduce this on 2.4.22 or similar? There have been so many changes
and fixes since 2.4.18.
There probably isn't any official documentation describing these drivers,
but you can take a look in the 'Documentation' directory in a recent linux
kernel tree - it may well have some good (and more general) USB driver
information.
