When ep1 receives CBW data, the isr routine is called. Then in isr, to get the usb_request: usb_request * req; req = list_entry(dev->ep[2].queue.next, struct kagen2_request, queue); however, the list_empty(&dev->ep[2].queue) is true. Where is the appropriate place to add list entry? thanks, victor -- 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
