Introduction

Hello,

   My name is Jerry Kaidor.  I've been using bitpim for a few years now. 
Now I have a sudden interest in developing....

   I just replaced my aged Sanyo MM-8300 with a sparkling new SCP-3810.  No
bitpim support.  In fact, there is no USB driver provided.  A cursory google
search did not unearth one.  Neither did the Sprint website.

   I'm willing to do some work to get support for my phone.  I'm a 
tolerably good programmer - I don't know Python, but have 25 years of
professional software development experience, mostly low-level C.  Lately,
I've written about twenty thousand lines of Perl.  And I know just enough
about USB to be dangerous :).

   The data cable that I bought at the Sprint store won't even charge the
phone on my winxp box without a driver to turn on the 5V.  Plugging it into
my Linux server gets me 

"usb 2-2: new full speed USB device using uhci_hcd and address 2"
"usb 2-2: configuration #1 chosen from 1 choice"
...and the phone is charging...

   So - what's the usual procedure for bringing up a new phone?   My first 
guess would be to:

   * Find the Linux source for a driver for a similar phone.
   * Dig into the Linux usb stuff ( /proc/bus/usb? ) to get the product ID and manufacturer ID 
     for my phone.  Or maybe find some sort of usb analyzer.

   * Hack the usb driver to try it out for my phone.  I suspect that most
     phones use one of those usb->Serial converter chips ( CP2102 etc ). 
     And it will look like a modem ( CDC-class USB device ).

   Or maybe to start, just get bitpim for Linux, compile it, run it, and see what
happens :).  

                                - Jerry Kaidor
