Thanks!
I wanted to answer before, but didn't have the time for proper testing.
I would like to know how you tacled the unusual_devs.h - I tried this
myself before but gave up because it seemed too many possible
combinations to try.

I have a Praktica(Pentacon) DCZ 2.1 and was not able to get it running
with Linux befor (see my mail from January the 15th on this list,
Message-Id: <[EMAIL PROTECTED]>).
I'm currently running kernel 2.4.18 (stock SuSE 8.0) with
/* Driver for USB Mass Storage compliant devices

Now taking your patch for unusual_devs.h, I gave it another go:

The result is, that it sometimes works, but most times it does not.
I have compiled the usb-storage with and without DEBUG switched on.
When it works, /var/log/messages looks like this:

I can then mount /dev/sda1 and do all the things you would expect to be
able to do.
Now, as I said, success is not guaranteed. In fact, most of the times it
fails. Without DEBUG switched on, the messages look like this:

Can anybody tell from the debug output what goes wrong here? And any
idea, why it sometimes works and sometimes not?
