Ben Hutchings 5377adb092 usb: Use the USB_SS_MULT() macro to decode burst multiplier for log message
usb_parse_ss_endpoint_companion() now decodes the burst multiplier
correctly in order to check that it's <= 3, but still uses the wrong
expression if warning that it's > 3.

Mathias Nyman ff30cbc8da usb: Use the USB_SS_MULT() macro to get the burst multiplier.
Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.

Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.

Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.

James P Michels III cd83ce9e61 usb-core bInterval quirk
This patch adds a usb quirk to support devices with interupt endpoints
and bInterval values expressed as microframes. The quirk causes the
parse endpoint function to modify the reported bInterval to a standards
conforming value.

There is currently code in the endpoint parser that checks for
bIntervals that are outside of the valid range (1-16 for USB 2+ high
speed and super speed interupt endpoints). In this case, the code assumes
the bInterval is being reported in 1ms frames. As well, the correction
is only applied if the original bInterval value is out of the 1-16 range.

With this quirk applied to the device, the bInterval will be
accurately adjusted from microframes to an exponent.

Julius Werner d86db25e53 usb: Make DELAY_INIT quirk wait 100ms between Get Configuration requests
The DELAY_INIT quirk only reduces the frequency of enumeration failures
with the Logitech HD Pro C920 and C930e webcams, but does not quite
eliminate them. We have found that adding a delay of 100ms between the
first and second Get Configuration request makes the device enumerate
perfectly reliable even after several weeks of extensive testing. The
reasons for that are anyone's guess, but since the DELAY_INIT quirk
already delays enumeration by a whole second, wating for another 10th of
that isn't really a big deal for the one other device that uses it, and
it will resolve the problems with these webcams.

There is no need to skip querying the config and string descriptors for
unauthorized WUSB devices when usb_new_device is called.  It is allowed
by WUSB spec.  The only action that needs to be delayed until
authorization time is the set config.  This change allows user mode
tools to see the config and string descriptors earlier in enumeration
which is needed for some WUSB devices to function properly on Android
systems.  It also reduces the amount of divergent code paths needed
for WUSB devices.

Lan Tianyu 3a22b872e9 usb: Fail a get config when the port is powered off.
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&m=134130616707548&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.

usb_parse_ss_endpoint_companion() was supposed to allocate a structure to

However, the previous code would miss the last endpoint in a configuration
with no descriptors after it.  Make usb_parse_endpoint() allocate the SS
endpoint companion descriptor and fill it with default values, even if

Sarah Sharp 663c30d082 USB: Parse and store the SuperSpeed endpoint companion descriptors.
The USB 3.0 bus specification added an "Endpoint Companion" descriptor that is
supposed to follow all SuperSpeed Endpoint descriptors.  This descriptor is used
to extend the bus protocol to allow more packets to be sent to an endpoint per
"microframe".  The word microframe was removed from the USB 3.0 specification
because the host controller does not send Start Of Frame (SOF) symbols down the
USB 3.0 wires.

The descriptor defines a bMaxBurst field, which indicates the number of packets
of wMaxPacketSize that a SuperSpeed device can send or recieve in a service
interval.  All non-control endpoints may set this value as high as 16 packets
(bMaxBurst = 15).

The descriptor also allows isochronous endpoints to further specify that they
can send and receive multiple bursts per service interval.  The bmAttributes
allows them to specify a "Mult" of up to 3 (bmAttributes = 2).

Bulk endpoints use bmAttributes to report the number of "Streams" they support.
This was an extension of the endpoint pipe concept to allow multiple mass
storage device commands to be outstanding for one bulk endpoint at a time.  This
should allow USB 3.0 mass storage devices to support SCSI command queueing.
Bulk endpoints can say they support up to 2^16 (65,536) streams.

The information in the endpoint companion descriptor must be stored with the
other device, config, interface, and endpoint descriptors because the host
controller needs to access them quickly, and we need to install some default
values if a SuperSpeed device doesn't provide an endpoint companion descriptor.

Sarah Sharp 6b403b020c USB: Add SuperSpeed to the list of USB device speeds.
Modify the USB core to handle the new USB 3.0 speed, "SuperSpeed".  This
is 5.0 Gbps (wire speed).  There are probably more places that check for
speed that I've missed.

SuperSpeed devices have a 512 byte endpoint 0 max packet size.  This shows
up as a bMaxPacketSize0 set to 0x09 (see table 9-8 of the USB 3.0 bus
spec).

xHCI spec says that the xHC can handle intervals up to 2^15 microframes.  That
might change when real silicon becomes available.

Add FIXME note for SuperSpeed isochronous endpoints.  They can transmit up
to 16 packets in one "burst" before they wait for an acknowledgment of the
packets.  They can do up to 3 bursts per microframe (determined by the
mult value in the endpoint companion descriptor).  The xHCI driver doesn't
have support for isoc yet, so fix this later.

David Brownell caa9ef672a USB: ehci tolerates some buggy devices
This teaches EHCI how to to work around bugs in certain high speed
devices, by accomodating "bulk" packets that exceed the 512 byte
constant value required by the USB 2.0 specification.  (Have a
look at section 5.8.3, paragraphs 1 and 3.)

It also makes the descriptor parsing code warn when it encounters
such bugs.  (We've had reports of maybe two or three such devices,
all pretty recent.)

Such devices are nonconformant.  The proper fix is have the vendors
of those devices do the simple, obvious, and correct thing ... which
will let them be used with USB hosts that don't have workarounds for
this particular vendor bug.  But unless/until they do, we can at least
have one of the high speed HCDs work with such buggy devices.
