Hi guys! I found the missing part at electronic store saturday and manage to fix it without too many problems.
Now I have my 1200 equipped with 4 USB ports! :-)
The Subway USB adapter is great! Almost every USB devices I tried like flash card reader, USB key, mouse, keyboard was working perfectly. Only my Wacom Graphire Tablet doesn't work :-( The tablet freeze only few seconds after you start using it. Too bad, I'd really like to use it with Brilliance and Photogenic.
The Poseidon USB stack that came with the adapter is a very nice piece of software. It's always impress me what Amiga programmers can do.
Thanks for the help!
