USB: Move vendor subclass definition from usb/audio.h to usb/ch9.h

2009-09-23T13:46:19+00:00

USB_SUBCLASS_VENDOR_SPEC is common to several USB classes and as such belongs
to usb/ch9.h.

USB: Move endpoint sync type definitions from usb/audio.h to usb/ch9.h

2009-09-23T13:46:19+00:00

And use the new definitions in the USB Audio Class gadget driver.

USB: Change names of SuperSpeed ep companion descriptor structs.

2009-06-16T04:44:50+00:00

Differentiate between SuperSpeed endpoint companion descriptor and the
wireless USB endpoint companion descriptor.  Make all structure names for
this descriptor have "ss" (SuperSpeed) in them.  David Vrabel asked for
this change in http://marc.info/?l=linux-usb&m=124091465109367&w=2

USB: Parse and store the SuperSpeed endpoint companion descriptors.

2009-06-16T04:44:49+00:00

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.

USB: Add SuperSpeed to the list of USB device speeds.

2009-06-16T04:44:48+00:00

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.

USB: pedantic: spelling correction in comment for ch9.h

USB: allow libusb to talk to unauthenticated WUSB devices

2009-03-24T23:20:35+00:00

To permit a userspace application to associate with WUSB devices
using numeric association, control transfers to unauthenticated WUSB
devices must be allowed.

This requires that wusbcore correctly sets the device state to
UNAUTHENTICATED, DEFAULT and ADDRESS and that control transfers can be
performed to UNAUTHENTICATED devices.

USB: Move definitions from usb.h to usb/ch9.h

2009-03-24T23:20:27+00:00

The functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_is_isoc_in(epd)
usb_endpoint_is_isoc_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

are moved from include/linux/usb.h to include/linux/usb/ch9.h.
include/linux/usb/ch9.h makes more sense for these functions because they
only depend on constants that are defined in this file.

USB: fix comment about endianness of descriptors

2008-12-17T18:49:14+00:00

This patch fixes a comment and clarifies the documentation about the
endianness of descriptors. The current policy is that descriptors will
be little-endian at the API even on big-endian systems; however the
/proc/bus/usb API predates this policy and presents descriptors with
some multibyte fields byte-swapped.

USB: Add the USB 2.0 extension descriptor.

2008-05-02T17:25:54+00:00

This device descriptor was added by the recent USB Link Power Management (LPM)
ECN.  It indicates whether the USB device supports LPM.

This descriptor is grouped under a Binary Device Object Store (BOS) descriptor.
Update the BOS comments to indicate any USB device (not just wireless USB
devices) can implement BOS descriptors.
