Problem Description:
This message is for a developer.

I have a 3Com ADSL Modem USB (model 3CP4218). Now, this modem is
discontinued by 3Com.
However, in Spain this modem is wide sold. I am interested in develop a
driver for Linux.
I know this modem use Alcatel Dynamite chipset. But, I think this modem has
a different
usb interface compared with Alcatel Speedtouch modem from Alcatel (this has
a driver for Linux).
I think this modem works similar to Alcatel Speedtouch to load the
microcode: a program sends
microcode (init and main) to the modem and after the modem is ok to work. To
develop the driver
I need to know the procedure and endpoint functions from usb. I have a
little program at Linux
made by me to load the code but I don't know how endpoint functions work.
Before load microcode usb modem has: Vendor ID=0506 and Product ID=f002,
after microcode load
at Windows has: Vendor ID=0506 and Product ID=f003. Also endpoint functions
are different.

Before load code:

Could you explain me the procedure to load microcode and endpoint functions.
Also
I interest how to know ADSL state and ATM data from usb modem.
I'd like send microcode using bulk transfer mode.

Regards,
   Josep

I think 3Com is a good company. Please, help me.
