You need a USB host controller system with an OS that can enumerate USB, and you can get source or drivers for the platform.

There is no such thing to "convert" a USB device to something else in a simple way.

If it were me, I'd find a phone that has standard RS232 signalling.

No. These are _slave_ devices. They won't do what is needed here (he needs a USB host chip).

These are complete 'built' assemblies, based on the Vinculum chip, which will do what he wants (the phone is only seen by the PC as a 'comm' device). However the chip alone, is about 1/3rd the price, and he has already asked for something cheaper!...

Hi Roger, second one I listed is the chip itself, and the first one, the module, I gave as an example for him, to enable him to understand what is required.

yes I know, and I listed the IC, but won't if cost him more than the price of a chip, and devise a means of somehow hooking up to an IC and I/O connectors, and get it running?

reality is, for a one off, you would be lucky to do it cheaper, let alone the time involved it getting it all running.

But if he can, fine! :-)

I gave him all the options to look at in the Vinculum family, and make a judgement based on having the info at his fingertips.

Cheers Don...
