USB drivers do not get interrupts like PCI devices do, they submit urbs and get called back when they are completed. Try reading the chapter on USB drivers in the book, "Linux Device Drivers, third edition", free online, to learn more about the USB driver model. If you have further questions, please ask them on the linux-usb-devel mailing list. good luck, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
