Thanks. Let me try to be more precise about something I don't understand in any detail. I believe that support for TCP/IP is built into the USB host drivers on most recent Linux and Win desktops, and that the Zaurus has drivers for its slave USB connection which support TCP/IP communication through the USB host.
Is it known that the drivers for the 6000 USB host, unlike those for Linux desktops, don't have this capability? If not, would supplying it be a matter of recompiling or more like a port or re-write? Given the hardware differences, I'm guessing there's probably lot's more to do than simply recompiling. Oh well. . . .
