Hello,

I am using a Motorola MxL chip. It has USB module. I
want to port it to linux usb subsystem so my device
can connect to desktop linux e.g. RH9 through USB.
I have read through the Linux USB guild. I would like
to know more specific information about porting USB
hardware module to subsystem, e.g. modifify which
files.

Use the pxa2xx_udc driver, in 2.6.2, as an example of how to do this. You'll need to write a driver for the controller, and it may need integration with board-specific setup (using platform_data) depending on how those chips work (do they need GPIOs for the USB connections etc). Look in drivers/usb/gadget and see where the trail leads.

Thanks a lot.
