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

2009-03-24T23:20:44+00:00

Just noticed this during a grep, figured I might as well send it in.

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.

USB: Standardize inclusion protection and add where missing.

2008-04-25T04:16:42+00:00

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

USB: defines for USB "Link Power Management" (LPM) ECN

2008-04-25T04:16:34+00:00

There's a new PM-related change notice for the USB 2.0 specification
called "Link Power Management" (LPM).  It defines a new "L1 Suspend"
state which resembles the current (L2) suspend state, except that it
can be entered and exited much more quickly.  It should thus be more
useful for runtime PM, even though it doesn't mandate reduced power
draw from VBUS.

This patch provides the relevant #defines for usbcore.  Actually
implementing these mechanisms requires host silicon that can generate
new USB packets, plus hubs handling some new requests and peripherals
which understand the new packets.

USB: add USB_DT_CS_RADIO_CONTROL define to ch9.h

2008-04-25T04:16:33+00:00

This is needed by the wireless usb developers, and is part of the USB spec.

USB: minor doc update

Minor doc update to  ... say where USB_DT_CS_* came
from and update the definitions to match how they're derived there.

USB: add rationale on why usb descriptor structures have to be packed

2007-02-23T23:03:46+00:00

Add argumentation in defense of using __attribute__((packed)) in USB
descriptors authored by Dave Brownell. Necessary as in some cases it
seems superfluous.
