2008-04-24USB: Remove EXPERIMENTAL from dynamic USB minor allocation.Robert P. J. Day
Since this USB feature seems non-experimental, remove that dependency. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-04-24USB: partial USB embedded host supportRobin Getz
This provides better support for USB "Embedded Host" functionality, which is a subset of the USB OTG options: * External hub support can be disabled; * USB peripherals not whitelisted in "otg_whitelist.h" will be rejected during enumeration. These options can allow some savings in software and support.

2008-04-24USB: remove CONFIG_USB_PERSIST settingAlan Stern
This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.

2008-03-04USB: update Kconfig entry for USB_SUSPENDAlan Stern
This patch (as1039) updates the Kconfig entry for USB_SUSPEND. The out-of-date reference to "power/state" is fixed, autosuspend is mentioned, and the dependency on EXPERIMENTAL is removed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-02-01USB: always announce a device has been added to the systemGreg Kroah-Hartman
Distros (like SuSE) want to know this information, to make it easier to handle support issues. Might as well let everyone benefit from this. This is also enabled whenever CONFIG_USB_DEBUG is enabled, to help with debugging. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-12USB: add power/persist device attributeAlan Stern
This patch (as920) adds an extra level of protection to the USB-Persist facility. Now it will apply by default only to hubs; for all other devices the user must enable it explicitly by setting the power/persist device attribute. The disconnect_all_children() routine in hub.c has been removed and its code placed inline. This is the way it was originally as part of hub_pre_reset(); the revised usage in hub_reset_resume() is sufficiently different that the code can no longer be shared. Likewise, mark_children_for_reset() is now inline as part of hub_reset_resume(). The end result looks much cleaner than before. The sysfs interface is updated to add the new attribute file, and there are corresponding documentation updates.

2007-07-12USB: add USB-Persist facilityAlan Stern
This patch (as886) adds the controversial USB-persist facility, allowing USB devices to persist across a power loss during system suspend. The facility is controlled by a new Kconfig option (with appropriate warnings about the potential dangers); when the option is off the behavior will remain the same as it is now. But when the option is on, people will be able to use suspend-to-disk and keep their USB filesystems intact -- something particularly valuable for small machines where the root filesystem is on a USB device!

2007-04-27USB: make usbdevices export their device nodes instead of using a separate classKay Sievers
o The "real" usb-devices export now a device node which can populate /dev/bus/usb. o The usb_device class is optional now and can be disabled in the kernel config. Major/minor of the "real" devices and class devices are the same. o The environment of the usb-device event contains DEVNUM and BUSNUM to help udev and get rid of the ugly udev rule we need for the class devices. o The usb-devices and usb-interfaces share the same bus, so I used the new "struct device_type" to let these devices identify themselves. This also removes the current logic of using a magic platform-pointer. The name of the device_type is also added to the environment which makes it easier to distinguish the different kinds of devices on the same subsystem. It looks like this: add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 ACTION=add DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1 SUBSYSTEM=usb SEQNUM=1533 MAJOR=189 MINOR=131 DEVTYPE=usb_device PRODUCT=46d/c03e/2000 TYPE=0/0/0 BUSNUM=002 DEVNUM=004 This udev rule works as a replacement for usb_device class devices: SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \ NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644" Updated patch, which needs the device_type patches in Greg's tree. I also got a bugzilla assigned for this. :) https://bugzilla.novell.com/show_bug.cgi?id=250659 Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-02-07usbcore: remove unused bandwith-related codeAlan Stern
This patch (as841) removes from usbcore a couple of support routines meant to help with bandwidth allocation. With the changes to uhci-hcd in the previous patch, these routines are no longer used anywhere. Also removed is the CONFIG_USB_BANDWIDTH option; it no longer does anything and is no longer needed since the HCDs now handle bandwidth issues correctly.

2007-01-22USB: disable USB_MULTITHREAD_PROBEGreg Kroah-Hartman
Disable the USB_MULTITHREAD_PROBE option because it causes crashes on people's machines and they never remember to actually read the config help files. No one likes this, everyone hates it, I'm going to go eat worms... The full logic will be ripped out later. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-12-01USB: create a new thread for every USB device found during the probe sequenceGreg Kroah-Hartman
Might speed up some systems. If nothing else, a bad driver should not take the whole USB subsystem down with it. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-04-14[PATCH] USB: otg hub support is optionalDavid Brownell
USB OTG devices are not required to support external hubs. This adds a configuration option to disable that support. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] root hub updates (greater half)David Brownell
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).

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
