[PATCH] USB: fix local variable clash

This patch (as621) fixes a local variable conflict I accidently
introduced into usb_set_configuration.

[PATCH] USB: Consider power budget when choosing configuration

2006-01-04T21:48:34+00:00

This patch (as609) changes the way we keep track of power budgeting for
USB hubs and devices, and it updates the choose_configuration routine to
take this information into account.  (This is something we should have
been doing all along.)  A new field in struct usb_device holds the amount
of bus current available from the upstream port, and the usb_hub structure
keeps track of the current available for each downstream port.

Two new rules for configuration selection are added:

	Don't select a self-powered configuration when only bus power
	is available.

	Don't select a configuration requiring more bus power than is
	available.

However the first rule is #if-ed out, because I found that the internal
hub in my HP USB keyboard claims that its only configuration is
self-powered.  The rule would prevent the configuration from being chosen,
leaving the hub & keyboard unconfigured.  Since similar descriptor errors
may turn out to be fairly common, it seemed wise not to include a rule
that would break automatic configuration unnecessarily for such devices.

The second rule may also trigger unnecessarily, although this should be
less common.  More likely it will annoy people by sometimes failing to
accept configurations that should never have been chosen in the first
place.

The patch also changes usbcore's reaction when no configuration is
suitable.  Instead of raising an error and rejecting the device, now
the core will simply leave the device unconfigured.  People can always
work around such problems by installing configurations manually through
sysfs.

[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.
