I am working on a cable to allow Sony handhelds with a T-series connector to talk to a serial 56k modem. One thing that got me thinking was that the Clie also has the USB Rx and Tx lines... Could that be used to communicate with a USB device, provided a driver was written?


THANKS!

BTW: The Sony CLIE site has mechanical drawings, and pinouts for most of the connectors. They also have a schematic for building your own serial cradle

I don't think it applies to the lower end SL10, but the NZ90 does have "USB host" support.

It is currently only used for printing.
ie. You can directly connect a printer to your PDA and print. Only 3 Epson models are currently supported.

BUT the UsbHost interface library is not documented. I have yet to find any public documentation on writing drivers in general.

--------
All models of CLIE use USB for hot-syncing (ie. the CLIE is the slave, and the PC is the host/master)
