The /sys/kernel/debug/usb/devices file doesn't know about Wireless or
SuperSpeed USB. This patch (as1416b) teaches it, and updates the
Documentation/usb/proc_sub_info.txt file accordingly.

There are lots of ZTE USB id's currently not covered by usb/serial. Adds them,
to allow those devices to work properly on Linux.
While here, put the USB ID's for 0x2002/0x2003 at the sorted order.
This patch is based on zte.c file found on MF645.
PS.: The ZTE driver is commenting the USB ID for 0x0053. It also adds, commented,
an USB ID for 0x0026.
Not sure why, but I think that 0053 is used by their devices in storage mode only.
So, I opted to keep the comment on this patch.

In today linux-next I got a compile error on usb/host/isp1362-hcd:
drivers/usb/host/isp1362-hcd.c: In function ‘isp1362_hub_control’:
drivers/usb/host/isp1362-hcd.c:1680: error: ‘ohci’ undeclared (first use in this function)
The problem is when the CONFIG_USB_OTG option is enabled.
ohci variable is never declared and there isn't any CONFIG_USB_OTG dependent code
besides the portion defined in isp1362_hub_control.
So I think that maybe USB OTG support is not needed/supported.
This patch removes the CONFIG_USB_OTG dependent block so the driver can compile cleanly.

The composite gadget will OOPS if the host sends a control request
targetted to an interface of an un-configured composite device. This patch
prevents this.
The OOPS was observed during WHQL USB CV tests. With this patch, the device
STALLs as per requirement.
Failing test case: From host do the following. I used libusb-1.0
1) Set configuration to zero.
libusb_control_transfer(device_handle,
0, /* standard OUT */
0x9, /* setConfiguration */
0, 0, NULL, 0, 0);
2) Query current configuratioan.
libusb_control_transfer(device_handle,
0x80, /* standard IN*/
0x8, /* getConfiguration */
0, 0, data, 1, 0);
3) Send the non-standard ctrl transfer targetted to interface
libusb_control_transfer(device_handle,
0x81, /* standard IN to interface*/
0x6, /* getDescriptor */
0x2300, 0, data, 0x12, 0);

This patch (as1417) fixes a problem affecting some (or all) nVidia
chipsets. When the computer is shut down, the OHCI controllers
continue to power the USB buses and evidently they drive a Reset
signal out all their ports. This prevents attached devices from going
to low power. Mouse LEDs stay on, for example, which is disconcerting
for users and a drain on laptop batteries.
The fix involves leaving each OHCI controller in the OPERATIONAL state
during system shutdown rather than putting it in the RESET state.
Although this nominally means the controller is running, in fact it's
not doing very much since all the schedules are all disabled. However
there is ongoing DMA to the Host Controller Communications Area, so
the patch also disables the bus-master capability of all PCI USB
controllers after the shutdown routine runs.
The fix is applied only to nVidia-based PCI OHCI controllers, so it
shouldn't cause problems on systems using other hardware. As an added
safety measure, in case the kernel encounters one of these running
controllers during boot, the patch changes quirk_usb_handoff_ohci()
(which runs early on during PCI discovery) to reset the controller
before anything bad can happen.

The protocol code is set 00 in IAD and it's set to 01 in ACM control
interface descriptor in f_acm.c file. Due to this, windows is unable to

tdi_reset is already taking care of setting host mode for tdi devices.
Don't duplicate code in platform driver.
Make ehci_halt a nop if the controller is not in host mode (otherwise it
will fail), and let's ehci_reset do the tdi_reset.
We need to move hcd->has_tt flags before ehci_halt, in order ehci_halt
knows we are a tdi device.
Before the setup routine was doing :
- put controller in host mode
- ehci_halt
- ehci_init
- hcd->has_tt = 1;
- ehci_reset
Now we do :
- hcd->has_tt = 1;
- ehci_halt
- ehci_init
- ehci_reset
PS : now we handle correctly the device -> host transition.

to resemble platform_driver_probe.

The iManufatcurer, iProduct and iSerialNumber composite module
parameters were only used when the gadget driver registers
strings for manufacturer, product and serial number. If the
gadget never bothered to set corresponding fields in USB device
descriptors those module parameters are ignored.
This commit makes the parameters work even if the strings ID
have not been assigned. It also changes the way IDs are
overridden -- what IDs are overridden is now saved in
usb_composite_dev structure -- which makes it unnecessary to
modify the string tables the way previous code did.
The commit also adds a iProduct and iManufatcurer fields to the
usb_composite_device structure. If they are set, appropriate
strings are reserved and added to device descriptor. This makes
it unnecessary for gadget drivers to maintain code for setting
those. If iProduct is not set it defaults to
usb_composite_device::name; if iManufatcurer is not set
a default "<system> <release> with <gadget-name>" is used.
The last thing is that if needs_serial field of
usb_composite_device is set and user failed to provided
iSerialNumber parameter a warning is issued.

If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.
To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it. Instead, send the buffer to
the host and return to userspace. This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.
This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.
