    Hi All,

    I am connecting to Nokia phone, due to its output is only USB signal,
    even it can emulate com port at PC side, however, it need USB host
    ( and driver )

    I am implementing on embedded system, I believe you know what I need.

    Could you please adivce the sutible chip for me ?

    I want as cheap as possible.


    Best regards,
    Boki.

    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.

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

  6. 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.

    However the chip alone, is about 1/3rd the price, and he has
    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...
