OK. I will have a look at the tunings you suggested me.
Are there some more people working on the similarities/differences between=
=20
those two models ?

Before joining the list, I was playing with a USB command line interpreter=
=20
(called usb-robot) which allows sending bulk or control transfers.

It seems to be a very useful tool for prototyping (it can handles=20
specific-language scripts featuring USB commands).

I hope this set will be helpful for determining my model's exact protocol.

Would you have a more recent/complete version of your analysis (found here:=
=20
http://home.kabelfoon.nl/~bertrik/hp3300c/transfer.html) ?

Which particular points would you want me to investigate ?

ps: any additional documentation appreciated ;-)
