USB Ethernet driver

Hi All,

I am new to QNX drivers and also to QNX.
I have planned to write a USB Ethernet driver on my own.
I am not understanding where to start from.

Please help me to succeede.
Is there any document or basic template for the USB Ethernet driver.
I got the document for USB driver and Network driver but now
understanding how to merge these two.

Please help me.
