Phil Dibowitz 93362a875f USB delay init quirk for logitech Harmony 700-series devices
The Logitech Harmony 700 series needs an extra delay during
initialization.  This patch adds a USB quirk which enables such a delay
and adds the device to the quirks list.

Hans de Goede 317149c655 USB: Add a new quirk: USB_QUIRK_HONOR_BNUMINTERFACES
Add a new quirk USB_QUIRK_HONOR_BNUMINTERFACES, when this quirk is
set and a device has more interface descriptors in a configuration
then it claims to have in config->bNumInterfaces, ignore all additional
interfaces.

This is needed for devices which try to hide unused interfaces by only
lowering config->bNumInterfaces, and which can't handle if you try to talk
to the "hidden" interfaces.

Oliver Neukum 5d3987796c USB: storage: Never reset devices that will morph to an old mode
Some devices must be switched to a new mode to fully use them.
A reset would make them revert to the old mode. Therefore a reset
must not be used for error handling with such devices.

Alan Stern 1662e3a7f0 USB: add quirk to avoid config and interface strings
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.

Robert P. J. Day dda43a0e03 USB: Standardize inclusion protection and add where missing.
For the header files in include/linux/usb, add missing multiple
inclusion protection and standardize what's already there.  The
apparent standards:

  * macro name of __LINUX_USB_headerfile_H
  * inclusion protection placed after leading comment block
  * macro name added as a comment on the final #endif
  * any obvious trivial whitespace cleanup associated with the above

Alan Stern 392e1d9817 USB: new quirk flag to avoid Set-Interface
This patch (as1057) fixes a problem with the X-Rite/Gretag-Macbeth
Eye-One Pro display colorimeter; the device crashes when it receives a
Set-Interface request.  A new quirk (USB_QUIRK_NO_SET_INTF) is
introduced and a quirks entry is created for this device.

Alan Stern a691efa988 USB: remove USB_QUIRK_NO_AUTOSUSPEND
This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk.  Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended.  Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID.  I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.

The patch also cleans up the hasty way in which autosuspend gets
disabled.  Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ.  It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.

Alan Stern 6bc6cff52e USB: add RESET_RESUME device quirk
This patch (as888) adds a new USB device quirk for devices which are
unable to resume correctly.  By using the new code added for the
USB-persist facility, it is a simple matter to reset these devices
instead of resuming them.  To get things kicked off, a quirk entry is
added for the Philips PSC805.

Oliver Neukum 7ceec1f1d2 USB: add a blacklist for devices that can't handle some things we throw at them.
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.
