Have you ever compiled a kernel before? The work involved is going to be very similar.

Linux already has a dummy network driver which you could derive yours from. In the linux source code, look in drivers/net/dummy.c You might also find drivers/net/loopback.c useful.

First thing to try for would be just printing a message into the dmesg buffer, that's not difficult, I think it's just kprintf... After that you might want to have it create a file under /proc/ somewhere for things to read from; when traffic or whatever happens, and someone's opened that file, they can read from it. That's the proper way to interface since the kernel's not supposed to reach into the guts of userspace and do things without being asked.

uhmodem

UHMODEM(4)						   BSD Kernel Interfaces Manual 						UHMODEM(4)

NAME

     uhmodem -- USB support for Huawei 3G wireless modem device

SYNOPSIS

     uhmodem*  at uhub?
     ucom*  at uhmodem?

HARDWARE

     The uhmodem driver supports the following adapters:

	   Huawei E220
	   E-mobile D01HW
	   E-mobile D02HW
	   NTT DoCoMo a2502

DESCRIPTION

     The uhmodem driver provides support for the Huawei 3G wireless modems and its variants.  This type of device has multiple com ports.  And
     some modems have own storage to contain its device driver (for Windows).  The uhmodem driver can handle all of these functions on the device.

     When the device attached, it will attach multiple ucom devices.  The former one is main com device to use communication with your network
     provider, and others are sub com devices to monitor the condition of data communication and/or network status.  These com devices can be used
     simultaneously.

     The device is accessed through the ucom(4) driver which makes it behave like a tty(4).

SEE ALSO

     tty(4), ubsa(4), ucom(4), usb(4)

HISTORY

     The uhmodem driver first appeared in NetBSD 5.0.  Separate from ubsa driver.
