The change to make DMA work two bytes at a time omitted an important tweak that affects the file_storage gadget: it needs to recognize when the host writes an odd number of bytes. (The network layer ignores such extra bytes.) This patch resolves that issue by checking the relevant bit and adjusting the rx byte count, so that for example a legal 13 byte request doesn't morph into an illegal 14 byte one any more.

The uhci-hcd driver is fairly lax about the way it handles isochronous transfers. This patch (as579) improves it in three respects: TDs for a new URB aren't added to the schedule until all of them have been allocated. This way there's no risk of the controller executing some of them when an allocation fails. TDs for an unlinked URB are removed from the schedule as soon as the URB is unlinked, rather than waiting until the URB is given back. This way there's no risk of the controller still executing a TD after the URB completes. The urb->error_count values are now reported correctly. Although since they aren't used in any drivers except for debug messages in the system log, probably nobody cares.

This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

This patch (as574) updates the PCI BIOS usb-handoff code for UHCI controllers, making it work like the reset routines in uhci-hcd. This allows uhci-hcd to drop its own routines in favor of the new ones (code-sharing). Once the patch is merged we can turn the usb-handoff option on permanently, as far as UHCI is concerned. OHCI and EHCI may still have some issues. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

There appears to be one more case where the HP8200 CD writer devices are detected as flash readers - when the USB cable is replugged after use, with the power cable still connected. Oddly enough, the identify device command appears to 'fall through' when the devices are in this state, the status register reading exactly the same opcode as the command (0xA1) that was just executed. I think it's safe to label this behaviour as specific to HP8200 devices, I can't get the flash devices to respond like this. This patch should solve the last of the HP8200 issues which have cropped up recently.

Because there is no bulk_interrupt_message() routine and no USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt transfers as well as bulk transfers. This patch (as567) formalizes this practice and adds code to usb_bulk_message() for detecting when the target is really an interrupt endpoint. If it is, the routine submits an interrupt URB (using the default interval) instead of a bulk URB. In theory this should help HCDs that don't like it when people try to mix transfer types, queuing both periodic and non-periodic types for the same endpoint. Not fully tested -- I don't have any programs that use USBDEVFS_BULK for interrupt transfers -- but it compiles okay and normal bulk messages work as well as before.

The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ... This patch makes it do so by: - Resetting the controller after kicking BIOS off, matching the normal "chip in hardware reset" startup mode; - Reporting any BIOS that borks this simple handoff; it's likely got a few other surprises for us too. - Ignoring that handoff on HPPA; The diagnostic string is mostly shared with EHCI, saving a few bytes.

This simplifies the OHCI root hub suspend logic: - Uses new usbcore root hub calls to make autosuspend work again: * Uses a newish usbcore root hub wakeup mechanism, making requests to khubd not keventd. * Uses an even newer sibling suspend hook. - Expect someone always made usbcore call ohci_hub_suspend() before bus glue fires; and that ohci_hub_resume() is only called after that bus glue ran. Previously, only CONFIG_USB_SUSPEND promised those things. (Includes updates to PCI and OMAP bus glue.) - Handle a not-noticed-before special case during resume from one of the swsusp snapshots when using "usb-handoff": the controller isn't left in RESET state. (A bug to fix in the usb-handoff code...) Also cleans up a minor debug printk glitch, and switches an mdelay over to an msleep (how did that stick around for so long?).

This updates the PCI glue to address the new and simplified usbcore suspend semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because hcd->hub_suspend() will always be called. - Removes now-unneeded recursion support - Go back to ignoring faults reported by the wakeup calls; we expect them to fail sometimes, and that's just fine.

This patch associates hub suspend and resume logic (including for root hubs) with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying two troublesome versions of suspend logic into just one. It'll be easier to keep things right from now on. - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of only when USB_SUSPEND is enabled: * Those root hub methods are now called from hub suspend/resume; no more skipping between layers during device suspend/resume; * It now handles cases allowed by sysfs or autosuspended root hubs, by forcing the hub interface to resume too. - All devices, including virtual root hubs, now get the same treatment on their resume paths ... including re-activating all their interfaces. Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and updates the Kconfig to match the new definition of USB_SUSPEND: it provides (a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream from any device configuration which supports it. This calls for minor followup patches for most HCDs (and their PCI glue).

This patch collects various small updates related to root hubs, to shrink later patches which build on them. - For root hub suspend/resume support: * Make the existing usb_hcd_resume_root_hub() routine respect pmcore locking, exporting and using the dpm_runtime_resume() method. * Add a new usb_hcd_suspend_root_hub() to pair with that routine. (Essential to make OHCI autosuspend behave again...) * HC_SUSPENDED by itself only refers to the root hub's downstream ports. So let HCDs see root hub URBs unless the parent device is suspended. - Remove an assertion we no longer need (and now, also don't want). - Generic suspend/resume updates to work better with swsusp. * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to use it breaks the swsusp snapshots it's supposed to help (sigh). * On resume, mark devices as resumed right away, but then do nothing else if the device is marked NOTATTACHED. These changes shouldn't be very noticable by themselves.

This cleans up a small recent FIXME, ensuring that all the HCDs provide root hub suspend/resume methods. It also wraps the calls to those root suspend routines just like on the PCI "USB_SUSPEND not defined" cases, so non-PCI bus glue won't be as tempted to behave very differently.

This patch removes the extra usb_suspend_device() parameter. The original reason to pass that parameter was so that this routine could suspend any active children. A previous patch removed that functionality ... leaving no reason to pass the parameter. A close analogy is pci_set_power_state, which doesn't need a pm_message_t either. On the internal code path that comes through the driver model, the parameter is now used to distinguish cases where USB devices need to "freeze" but not suspend. It also checks for an error case that's accessible through sysfs: attempting to suspend a device before its interfaces (or for hubs, ports).
