I'll be getting a (long awaited) Picasso IV soon also with manual, hope it's in English, to replace the Picasso II in my A3000D. I wouldn't think I'd have to uninstall and then reinstall the Picasso96 drivers.
If the manual I recieve is indeed in english, I might somehow be persuaded to scan manual to .pdf :-D
...and no, the Picasso II will NOT be up for sale. Gonna stuff it into an A2000.
