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).

As the simplest example, if a USB mouse or keyboard is unplugged immediately after the computer is put to sleep, the unplug will cause the system to wake back up again!

Wysocki" Date: Tue, 20 Jan 2009 01:26:56 +0100 Subject: [PATCH 05/36] USB: Fix suspend-resume of PCI USB controllers Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703 (USB: fix up suspend and resume for PCI host controllers) attempted to fix the suspend-resume of PCI USB controllers, but unfortunately it did that incorrectly and interrupts are left enabled by the USB controllers' ->suspend_late() callback as a result. This leads to serious problems during suspend which are very difficult to debug. Fix the issue by removing the ->suspend_late() callback of PCI USB controllers and moving the code from there to the ->suspend() callback executed with interrupts enabled. Additionally, make the ->resume() callback of PCI USB controllers execute pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the full power state (PCI_D0). Signed-off-by: Rafael J.

As a result, the code to send a disconnect signal to userspace would not be built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were disabled. The usb_fs_classdev_common_remove() routine has been renamed to usbdev_remove() and it is now called whenever any USB device is removed, not just when a class device is unregistered. The notifier registration and unregistration calls are no longer conditionally compiled. And since the common removal code will always be called as part of the char device interface, there's no need to call it again as part of the usbfs interface; thus the invocation of usb_fs_classdev_common_remove() has been taken out of usbfs_remove_device().
