While reading the config parsing code I noticed this check is missing, without
this check config-&gt;desc.wTotalLength can end up with a value larger then the
dev-&gt;rawdescriptors length for the config, and when userspace then tries to
get the rawdescriptors bad things may happen.

<title>usb: Fail a get config when the port is powered off.</title>

Alan Stern pointed out that a USB port could potentially get powered off
when the attached USB device is in the middle of enumerating, due to
race conditions:
	http://marc.info/?l=linux-usb&amp;m=134130616707548&amp;w=2

If that happens, we need to ensure the enumeration fails.  If a call to
usb_get_descriptor() fails for a reason other than a Stall, return an
error.  That should handle the case where the port is powered off.

This commit gets BOS(Binary Device Object Store) descriptor set for Super
Speed devices and High Speed devices which support BOS descriptor.

BOS descriptor is used to report additional USB device-level capabilities
that are not reported via the Device descriptor. By getting BOS descriptor
set, driver can check device's device-level capability such as LPM
capability.

Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size

wMaxPacketSize is __le16 and should be accessed as such. Also fix the
wBytesPerInterval assignment while here.

v2: also fix the wBytesPerInterval assigment, noticed by Matt Evans

This patch should be backported to the 3.0 kernel.

This patch (as1375) eliminates the usb_host_ss_ep_comp structure used
for storing a dynamically-allocated copy of the SuperSpeed endpoint
companion descriptor.  The SuperSpeed descriptor is placed directly in
the usb_host_endpoint structure, alongside the standard endpoint
descriptor.

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-&gt;bNumInterfaces, ignore all additional
interfaces.

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

The usbcore headers: hcd.h and hub.h are shared between usbcore,
HCDs and a couple of other drivers (e.g. USBIP modules).
So, it makes sense to move them into a more public location and
to cleanup dependency of those modules on kernel internal headers.
This patch moves hcd.h from drivers/usb/core into include/linux/usb/
