**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
To have a major number allocated, or a minor number in situations
where that applies (e.g. busmice), please contact me with the
appropriate device information. Also, if you have additional
information regarding any of the devices listed below, or if I have
made a mistake, I would greatly appreciate a note.

I do, however, make a few requests about the nature of your report.
This is necessary for me to be able to keep this list up to date and
correct in a timely manner. First of all, *please* send it to the
correct address... <device@lanana.org>. I receive hundreds of email
messages a day, so mail sent to other addresses may very well get lost
in the avalanche. Please put in a descriptive subject, so I can find
your mail again should I need to. Too many people send me email
saying just "device number request" in the subject.

Second, please include a description of the device *in the same format
as this list*. The reason for this is that it is the only way I have
found to ensure I have all the requisite information to publish your
device and avoid conflicts.

Third, please don't assume that the distributed version of the list is
up to date. Due to the number of registrations I have to maintain it
in "batch mode", so there is likely additional registrations that
haven't been listed yet.

Finally, sometimes I have to play "namespace police." Please don't be
offended. I often get submissions for /dev names that would be bound
to cause conflicts down the road. I am trying to avoid getting in a
situation where we would have to suffer an incompatible forward
change. Therefore, please consult with me *before* you make your
device names and numbers in any way public, at least to the point
where it would be at all difficult to get them changed.
