USB: handle errors in power/level attribute

2007-05-23T06:45:50+00:00

This patch (as906) improves the error handling for the USB power/level attribute file. If an error occurs, the original power-level settings will be restored. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: add "busnum" attribute for USB devices

2007-04-27T20:28:42+00:00

This patch (as903) adds a "busnum" sysfs attribute for USB devices. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: add power/level sysfs attribute

2007-04-27T20:28:37+00:00

This patch (as874) adds another piece to the user-visible part of the USB autosuspend interface. The new power/level sysfs attribute allows users to force the device on (with autosuspend off), force the device to sleep (with autoresume off), or return to normal automatic operation.

USB: Allow autosuspend delay to equal 0

2007-04-27T20:28:35+00:00

This patch (as867) adds an entry for the new power/autosuspend attribute in Documentation/ABI/testing, and it changes the behavior of the delay value. Now a delay of 0 means to autosuspend as soon as possible, and negative values will prevent autosuspend. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: export autosuspend delay in sysfs

2007-02-23T23:03:47+00:00

This patch (as861) adds sysfs attributes to expose the autosuspend delay value for each USB device. If the user changes the delay from 0 (no autosuspend) to a positive value, an autosuspend is attempted. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: minor cleanups for sysfs.c

2007-02-23T23:03:46+00:00

This patch (as858) makes some minor cleanups to sysfs.c in usbcore. Unnecessary tests are removed and a few temp variables are added. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: add a blacklist for devices that can't handle some things we throw at them.

2007-02-23T23:03:46+00:00

This adds a blacklist to the USB core to handle some autosuspend and string issues that devices have. Originally written by Oliver, but hacked up a lot by Greg. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: unconfigure devices which have config 0

2007-02-16T23:32:21+00:00

Some USB devices do have a configuration 0, in contravention of the USB spec. Normally 0 is supposed to indicate that a device is unconfigured. While we can't change what the device is doing, we can change usbcore. This patch (as852) allows usb_set_configuration() to accept a config value of -1 as indicating that the device should be unconfigured. The request actually sent to the device will still contain 0 as the value. But even if the device does have a configuration 0, dev->actconfig will be set to NULL and dev->state will be set to USB_STATE_ADDRESS. Without some sort of special-case handling like this, there is no way to unconfigure these non-compliant devices. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

usbcore: trivial whitespace fixes

2007-02-07T23:44:40+00:00

This patch (as844) makes some trivial whitespace fixes to a few files in usbcore. Oliver did most of the work and Alan added some tidying up. Signed-off-by: Oliver Neukum Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman
