This patch (as1200) finishes some fixes that were left incomplete by an earlier patch. Although nobody has addressed this issue in the past, it turns out that we need to distinguish between two different modes of disabling and enabling endpoints. In one mode only the data structures in usbcore are affected, and in the other mode the host controller and device hardware states are affected as well. The earlier patch added an extra argument to the routines in the enable_endpoint pathways to reflect this difference. This patch adds corresponding arguments to the disable_endpoint pathways. Without this change, the endpoint toggle state can get out of sync between the host and the device. The exact mechanism depends on the details of the host controller (whether or not it stores its own copy of the toggle values).
