[PATCH] USB: move CONFIG_USB_DEBUG checks into the Makefile

2005-11-17T19:29:55+00:00

This lets us remove a lot of code in the drivers that were all checking
the same thing.  It also found some bugs in a few of the drivers, which
has been fixed up.

[PATCH] usbcore: Fix handling of sysfs strings and other attributes

2005-10-28T23:47:51+00:00

This patch (as592) makes a few small improvements to the way device
strings are handled, and it fixes some bugs in a couple of other sysfs
attribute routines.  (Look at show_configuration_string() to see what I
mean.)

[PATCH] usbcore: Use kzalloc instead of kmalloc/memset

2005-10-28T23:47:51+00:00

This patch (as590) fixes up all the remaining places where usbcore can
use kzalloc rather than kmalloc/memset.

[PATCH] usbcore: endpoint attributes track altsetting changes

2005-10-28T23:47:51+00:00

This patch (as588) fixes the way endpoint attribute files are registered
and unregistered.  Now they will correctly track along with altsetting
changes.  This fixes bugzilla entry #5467.

In a separate but related change, when a usb_reset_configuration call
fails, the device state is not changed to USB_STATE_ADDRESS.  In the
first place, failure means that we don't know what the state is, not
that we know the device is unconfigured.  In the second place, doing
this can potentially lead to a memory leak, since usbcore might not
realize there still is a current configuration that needs to be
destroyed.

[PATCH] USB: usb_bulk_message() handles interrupts endpoints

2005-10-28T23:47:41+00:00

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.

[PATCH] usb_interface power state

2005-10-28T23:47:38+00:00

This updates the handling of power state for USB interfaces.

  - Formalizes an existing invariant:  interface "power state" is a boolean:
    ON when I/O is allowed, and FREEZE otherwise.  It does so by defining
    some inlined helpers, then using them.

  - Adds a useful invariant:  the only interfaces marked active are those
    bound to non-suspended drivers.  Later patches build on this invariant.

  - Simplifies the interface driver API (and removes some error paths) by
    removing the requirement that they record power state changes during
    suspend and resume callbacks.  Now usbcore does that.

A few drivers were simplified to address that last change.

[PATCH] driver core: add helper device_is_registered()

2005-09-22T14:58:24+00:00

add the helper and use it instead of open coding the klist_node_attached() check
(which is a layering violation IMHO)

[PATCH] USB: remove annoying message

2005-09-08T23:28:25+00:00

Avoid an annoying message that can appear if devices are disconnected
in the middle of a USB scatterlist operation.

Message noted in http://bugzilla.kernel.org/show_bug.cgi?id=4373
(but the real issue there seems to be a SCSI level hang).
