[Q] Question about A1200 usb chip or protocol

[geniusbabak]

Hi all
Has anybody any reference about the A1200 USB chip or its protocol ?
I was thinking of making some external devices work with A1200 like external keyboard, mouse, screen ...

Thanks in advance

that would be cool if we could connect those things. I have no Idea where to find that info though

Wow thanks PaulF, now the only remaining thing is the MontaVista SDK or just it's Interrupt table 'cause I need to hang my procedure on the OS main I/O procedure.

Montavista SDK???? Interrupt table?? main I/O procedure?
Why dont you just write a kernel module?

@Wyrm
I have no experience i writing kernel modules, but i can make hardware interface between miniUSB and many kinds of I/O devices, even I can make a switch to emulate more than one I/O port
if you are interested we can cooperate to make it happen

[wyrm]

there is a software controllable switch, on the usb transceiver that allows you to switch the usb port to audio, serial, usb device or usb host (unpowered). There is no need for hardware mods.

Nice idea. .all the best for your project

Dear wyrm
I think you did not understand my Idea correctly
I meant, we could have a module inside the phone to for example reading serial keyboard data from mini usb port and reading serial mouse data from usb port and ...
It will be it's simple version that we can connect just one peripheral device to A1200
But we can use some protocol and a hardware attaching to mini usb to use more than one device in one time like a mouse and a keyboard at same time

I can make the device to support multi usb or com devices at one time and I can make it to work with any protocol we invent for our ming.

So we will need some software installed in our ming to send and receive data from usb port and use them as text input or touch screen tap or hold (as left click and right click)

Babak
