      USB: pxa27x_udc: minor fixes · 5a59bc54
      Robert Jarzmik authored 
      Minor fixes to pxa27x udc driver :
 - don't clobber driver model bus_id field
 - wrong endianess fix (no functional change; cpu is little-endian)
 - double udc disable fix
 - resume/suspend fix (OTG hold bit)
 - make driver pxa27x dependant (check cpu at runtime)

      USB: remove PICDEM FS USB demo (04d8:000c) device from ldusb · 5fc89390
      Xiaofan Chen authored 
      Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
	http://forum.microchip.com/tm.aspx?m=106426&mpage=2

So I believe that the in-kernel ldusb driver will no longer work with the
demo firmware.  It should be removed.

      USB: unusual_devs: Add support for GI 0401 SD-Card interface · e7c6f80f
      Filip Aben authored 
      Enables the SD-Card interface on the GI 0401 HSUPA card from Option.

The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.

This revised patch adds a small comment explaining why and reduces the
rev range.

      USB: serial gadget: descriptor cleanup · b9370332
      David Brownell authored 
      Bugfix some serial gadget descriptors:

 - Stop mangling the low bits (controller type ID) of bcdDevice;
   just use the high bits for a driver revision code.

 - Serial numbers that aren't specific to individual devices
   are useless; stop reporting "0" for this.

 - Since it's not part of a CDC-conformant function, the "bulk only"
   configuration shouldn't be using "CDC Data" as its interface class.
   Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).

      USB: serial gadget: simplify endpoint handling · 734d37c6
      David Brownell authored 
      Switch serial gadget away from a *very* old idiom:  just remember
the endpoints we'll be using, instead of looking them up by name
each time.  This is a net code and data (globals) shrink.

Also fix a small memory leak in the rmmod path, by working the
same as the disconnect code.

      USB: serial gadget: remove needless data structure · 2c2d28a0
      David Brownell authored 
      This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.

Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

      USB: serial gadget: cleanup/reorg · 9079e91b
      David Brownell authored 
      Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.

 - Remove most forward declarations
     * put tty and gadget driver structs after their contents
     * snug module init/exit decls next to their functions
     * reordered some functions

 - Other cleanup:
     * convert a funky macro to an inline function
     * snug up module params next to their declarations
     * add missing driver.owner
     * add separator lines between major driver sections

 - Add comments re potential parameter/#define changes:
     * only supports one port (shrank GS_NUM_PORTS)
     * changing from 9600-8-N-1 affects multiple sites

 - Remove net2280-specific optimization ... it was being done
   way too late, can be done by net2280 module options, and in
   any case doesn't matter at any sane serial data rates.

There are no behavioral changes, but the macro thing saves I-space.

      USB: do not handle device 1410:5010 in 'option' driver · cdafc37a
      Eugeniy Meshcheryakov authored 
      This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:

lsusb -v -d 1410:5010 | grep InterfaceClass
      bInterfaceClass         8 Mass Storage

After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:

% lsusb -v -d 1410:4400 | grep InterfaceClass
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceClass       255 Vendor Specific Class

Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.

      The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:

May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

      USB: create attributes before sending uevent · 2e5f10e4
      Alan Stern authored 
      This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
one altsetting to another, so it has to be created dynamically.
