Retro-fit USB monitor
I'm at a loss. I want to retrofit a USB host driver with the calls necessary to implement USB monitoring but I can't find any good reference material. Can someone point me in the right direction? The usbmon.txt file does a nice job on using the facility but doesn't say much about the driver side.

You're in luck -- no changes to the driver are needed. The usbmon module and usbcore take care of everything for you. :-) Alan Stern -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

You shouldn't need to add any hooks into the host driver, the USB core should handle all of this automatically for you. thanks, greg k-h -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It's the gadget driver for the Freescale Dual role controller.

Re: Retro-fit USB monitor
Sorry about the poor form! Bad habit I suppose. That's a host-controller-only interface for now. That being usbmon - right? But there is no intrinsic reason I couldn't use the USB core as a model for retrofitting the Freescale DR driver is there? BTW - I haven't found any thing describing the difference between the uN and sN (eg u0 and s0) files.

I have no idea what driver you are referring to, why isn't it merged into the kernel tree already?

Did you read the usbmon documentation? thanks, greg k-h -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
