When a USB device is reset, the xHCI hardware must know, in order to match the device state and disable all endpoints except control endpoint 0. Issue a Reset Device command after a USB device is successfully reset. Wait on the command to finish, and then cache or free the disabled endpoint rings. There are four different USB device states that the xHCI hardware tracks: - disabled/enabled - device connection has just been detected, - default - the device has been reset and has an address of 0, - addressed - the device has a non-zero address but no configuration has been set, - configured - a set configuration succeeded. The USB core may issue a port reset when a device is in any state, but the Reset Device command will fail for a 0.96 xHC if the device is not in the addressed or configured state. Don't consider this failure as an error, but don't free any endpoint rings if this command fails. A storage driver may request that the USB device be reset during error handling, so use GPF_NOIO instead of GPF_KERNEL while allocating memory for the Reset Device command.

Add the hub emulation code to allow ports on an xHCI root hub to be disabled. Add the code to clear the port enabled/disabled bit, and clear the port enabled/disabled change bit. Like EHCI, the port cannot be enabled by setting the port enabled/disabled bit. Instead, a port is enabled by the host controller after a reset.

Refactor the code to clear the port change bits in the port status register. All port status change bits are write one to clear. Remove a redundant port status read that was supposed to unblock any posted writes. We read the port after the write to get the updated status for debugging, so the port read after that is unnecessary.

The xhci_command structure is the basic structure for issuing commands to the xHCI hardware. It contains a struct completion (so that the issuing function can wait on the command), command status, and a input context that is used to pass information to the hardware. Not all commands need the input context, so make it optional to allocate. Allow xhci_free_container_ctx() to be passed a NULL input context, to make freeing the xhci_command structure simple.

If we fail to queue an evaluate context command or a configure endpoint command to the command ring in xhci_configure_endpoint(), we need to remove the xhci_command structure from the device's command list before returning. If the command is left on the command list, it will sit there indefinitely, blocking commands submitted after this fails.

This patch (as1316) adds some error checking to usb_submit_urb(). It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users. The new check makes sure that the actual type of the endpoint described by urb->pipe agrees with the type encoded in the pipe value. The USB error code documentation is updated to include the code returned by the new check, and the usbfs SUBMITURB handler is updated to use the correct pipe type when legacy user code tries to submit a bulk transfer to an interrupt endpoint.

On various mxc boards, the intial ULPI reads resulted in a timeout which prevented the transceiver to be identified and thus the ehci device to be probed.

This has never worked properly because wsize passed to cxacru_cm() is incorrectly set to the number of values instead of the data bytes. The maximum number of values that can be set at once is 7 which means the device will not get enough data to work with and none of the configuration values will be used. At least one existing cxacru-cf.bin file contains invalid data which will prevent the modem from syncing properly. Fixing it is likely to break existing systems, and the new sysfs interface for setting configuration parameters can provide the same functionality.

The modem can be configured using CM_REQUEST_CARD_DATA_SET, although CM_REQUEST_CARD_DATA_GET does not return any data. Tested by setting the modulation (0x0a) option. There is a list of parameters in the following archive, but the meaning of many of them is not well documented: http://sourceforge.net/project/shownotes.php?release_id=301825 This source also indicates that the highest parameter set is 0x4a but this varies by model so an arbitrary limit of 0x7f has been used (the index is a 32-bit integer).

Firmware writing takes 256ms per 4KB with OHCI, which is very slow compared to 7ms per 4KB with UHCI. Until I have access to a hardware USB analyser it may not be possible to determine why this happens.

Move the access code to an inline function in usbatm.h, and return -ENODEV if any of the pointers are NULL.

Set power.async_suspend for USB devices, endpoints and interfaces, allowing them to be suspended and resumed asynchronously during system sleep transitions. The power.async_suspend flag is also set for devices that don't have suspend or resume callbacks, because otherwise they would make the main suspend/resume thread wait for their "asynchronous" children (during suspend) or parents (during resume), effectively negating the possible gains from executing these devices' suspend and resume callbacks asynchronously.

This patch (as1331) adds non-tree ordering constraints needed for proper resume of PCI USB host controllers from hibernation. The main issue is that non-high-speed devices must not be resumed before the high-speed root hub, because it is the ehci_bus_resume() routine which takes care of handing the device connection over to the companion controller. If the device resume is attempted before the handover then the device won't be found and it will be treated as though it had disconnected. The patch adds a new field to the usb_bus structure; for each full/low-speed bus this field will contain a pointer to the companion high-speed bus (if one exists). It is used during normal device resume; if the hs_companion pointer isn't NULL then we wait for the root-hub device on the hs_companion bus. A secondary issue is that an EHCI controlller shouldn't be resumed before any of its companions. On some machines I have observed handovers failing if the companion controller is reinitialized after the handover. Thus, the EHCI resume routine must wait for the companion controllers to be resumed. The patch also fixes a small bug in usb_hcd_pci_probe(); an error path jumps to the wrong label, causing a memory leak.

The five-second delay can be rather annoying, and makes the system appear much less responsive when you connect a USB drive. It's also not entirely clear that it is needed - the settling delay has at least historically been an issue on some Apple iPods, for example, and some devices have been reported to need even more than the old 5s delay. But before we penalize them all, let's see how bad it really is. Some of the reasons for long delays seem to be actual historical kernel bugs that should probably never have been papered over with a delay in the first place (there's a Ubuntu bug report for 2.6.20 about a NULL pointer dereference unless 'delay_use' is 8 or more, for example). It also looks like some distros have already shipped with delay_use=0, so the five second default may well be totally historical. In other words: "Let's see if anybody screams".
