USB: add speed values for USB 3.0 and wireless controllers

2010-01-25T18:49:34Z

commit b132b04e193908a94d95065d0628f8fb0159cc55 upstream. These controllers say "unknown" for their speed in sysfs, which obviously isn't correct. Reported-by: Kurt Garloff Cc: Sarah Sharp Cc: David Vrabel Signed-off-by: Greg Kroah-Hartman

USB: fix bugs in usb_(de)authorize_device

2010-01-06T23:03:46Z

commit da307123c621b01cce147a4be313d8a754674f63 upstream. This patch (as1315) fixes some bugs in the USB core authorization code: usb_deauthorize_device() should deallocate the device strings instead of leaking them, and it should invoke usb_destroy_configuration() (which does proper reference counting) instead of freeing the config information directly. usb_authorize_device() shouldn't change the device strings until it knows that the authorization will succeed, and it should autosuspend the device at the end (having autoresumed the device at the start). Because the device strings can be changed, the sysfs routines to display the strings must protect the string pointers by locking the device.

driver model: constify attribute groups

2009-09-15T16:50:47Z

Let attribute group vectors be declared "const". We'd like to let most attribute metadata live in read-only sections... this is a start. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: add quirk to avoid config and interface strings

2009-03-24T23:20:25Z

Apparently the Configuration and Interface strings aren't used as often as the Vendor, Product, and Serial strings. In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests. This patch (as1226) adds a quirks flag, telling the kernel not to read a device's Configuration or Interface strings, together with a new quirk for the offending joystick.

USB: utilize the bus notifiers

2009-01-07T18:00:08Z

This patch (as1185) makes usbcore take advantage of the bus notifications sent out by the driver core. Now we can create all our device and interface attribute files before the device or interface uevent is broadcast. A side effect is that we no longer create the endpoint "pseudo" devices at the same time as a device or interface is registered -- it seems like a bad idea to try registering an endpoint before the registration of its parent is complete. So the routines for creating and removing endpoint devices have been split out and renamed, and they are called explicitly when needed. A new bitflag is used for keeping track of whether or not the interface's endpoint devices have been created, since (just as with the interface attributes) they vary with the altsetting and hence can be changed at random times.

USB: Enhance usage of pm_message_t

2009-01-07T18:00:03Z

This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: straighten out inline code in sysfs.c

2009-01-07T17:59:50Z

This patch (as1156) straightens out some code in usbcore. The usb_create_intf_ep_files() and usb_remove_intf_ep_files() routines don't need to be separate inlines; they should be moved bodily into the places where they get used. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: don't register endpoints for interfaces that are going away

2008-11-13T22:45:00Z

This patch (as1155) fixes a bug in usbcore. When interfaces are deleted, either because the device was disconnected or because of a configuration change, the extra attribute files and child endpoint devices may get left behind. This is because the core removes them before calling device_del(). But during device_del(), after the driver is unbound the core will reinstall altsetting 0 and recreate those extra attributes and children. The patch prevents this by adding a flag to record when the interface is in the midst of being unregistered. When the flag is set, the attribute files and child devices will not be created.

USB: Export if an interface driver supports autosuspend.

2008-10-17T21:41:03Z

Create a new sysfs file per interface named supports_autosuspend. This file returns true if an interface driver's .supports_autosuspend flag is set. It also returns true if the interface is unclaimed (since the USB core will autosuspend a device if an interface is not claimed). This new sysfs file will be useful for user space scripts to test whether a USB device correctly auto-suspends. Signed-off-by: Sarah Sharp Cc: Oliver Neukum Signed-off-by: Greg Kroah-Hartman
