Sorry about the delayed reply - I have been away for a couple
of days.

Is that non-standard? I only see

It is all magic that I didn't know anything about till I started
trying to figure out how to get this phone to work ;)

That tells me that you (or at least your phone) has two configurations,
of which the first is the active one. The only significant
difference I can see is that the first has a much higher maximum
power requirement (500mA vs 100mA) - however both are quite a bit
higher than the 20mA of my phone's single configuaration...
Both of your configurations have two Interfaces, the first is a 'comm.' type
with one end point, and the second a 'data' with two Bulk endpoints.
Thus they both look more or less the same as the single config that I have.
I tried installing the latest kernel (2.6.12-r10) but that did not seem
to make any difference - I get the same protocol error message on
connection.
So currently I am at a bit of a loss. Unless you have some subtly
different settings in your kernel config, it is starting to look
like resolving this may require a deeper understanding of USB, the
Linux USB driver implementation and the protocols used by Motorola
phones than I currently posess (I do not have a copy of the Windows
software for the phone, so I can't check to see what it is doing
differently).
Here is what 'grep USB /usr/src/linux/.conf' produces for me - does
anything standout as being different to your config?

Only other thing I can think of is a problem with my cable. It is not
specifically made for the phone (it is from my MP3 player), but my
understanding is that USB is just a 4 wire protocol, so it the
connectors phsically fit the cable should be usable.
