Hi everyone, Although my C skills are very rusty I am trying to create a module for a webcam that utilizes the sn9c102 chip. Currently I have managed to create a very basic module that registers with the kernel and detects the device via the probe function. I have also initalised a usb_submit_urb on the 3rd endpoint (which is an interrupt type). The complete funtion works fine in that it detects when I press the button on the top of the webcam and writes a message to the kernel log (incrementing a count).
I am quite pleased at what I have achieved with this but want to move onto setting up the isosyncronous endpoint in order to transfer images (as this is the point of a webcam). BUT before I do that can someone point me in the right direction with regard to usb_unlink_urb() because I just can not get this to work for me in any useful shape or form. If I unjack my device something (evidently not the webcam itself if its offline) keeps calling endpoint 3 complete routine. I know its calling the disconnect function (as I get a message) but nothing happens after the unlink except as I said something keeps calling the complete function. Currently my only safe exit procedure is to reboot which as you could imagine is impacting on my development time ! I have tried the following reading manuals looking at other peoples code in drivers/usb everything but beating the computer around the monitor with a large stick. Non of which has made any impression on my synaptic processor Could someone please please please explain what the proper exit procedure is for the usb disconnect function. By the way Im using a 2.4.x kernel at the moment. Thanks in advance Tom. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
