You do a call to usb_put_hcd() and if there are no more references to that hcd, it is cleaned up and will eventually call back into your release() function that you set up in usb_create_hcd(). That's where you free the structure you created. Hope this helps, greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
