[NTLK] USB-001 and Snow Leopard

On a photo I saw that KN uses an FTDI chip: the FT232R. The driver for that chip is available form the manufacturer for pretty much any OS here:


Make sure you download the correct driver for your OS, 32 or 64 bits, and for OS X, Intel or PPC. Let me know if this helps. Also make sure you set the transfer rate to the lowest setting. NewtonOS can not handle a full speed stream (which is why you need to use "slowdown.exe" on fast PCs).

If there is anyone in Germany or the EU who has a non-working board that is collecting dust, I'll be happy to take a look at it and test it with my MP2100 and OS X Lion.

PS: I often have tons to do at work which means that it may take quite a while before I can send your board back :-(

I've tried to no avail, although it works on the dual-boot WinXP partition without even needed a driver install (I think XP found what it needed in its auto-search once it detected the MP200 as a "unknown USB device".
>> Knowledge Navigator kept telling me to install the KeySpan USA-28 driver for OSX but this is for the KeySpan serial to USB adapter unit, is already installed (as I use the Keyspan for my eMate), and reinstalling it has no effect.  I cannot see any reference to USB in the drop down connection menu in NCX's preferences (only Keyspan1, USA28Xfd14p1.1, USA28Xfd14P2.2 all of which have always been there). System Profiler detects a "FX232R USB UART" when the MP2000 is plugged in via USB though.  I'm at a loss!
