Make a dedicated structure for datagram pointer entry. There is no explicit declaration in the spec, but it's used by the host implementation and makes the structure more clear. Add some missed constants from the spec Signed-off-by:

This patch, adds to the option driver the Onda Communication (http://www.ondacommunication.com) vendor id, and the MT825UP modem device id. Note that many variants of this same device are being release here in Italy (at least one or two per telephony operator). These devices are perfectly equivalent except for some predefined settings (which can be changed of course). It should be noted that most ONDA devices are allready supported (they used other vendor's ids in the past). The patch seems working fine here, and the rest of the driver seems uninfluenced.

The un-registration of OHCI driver was not done in the ohci_hcd_mod_exit function. This was affecting rmmod command not to work for OMAP3 platforms. The platform driver un-registration for OMAP3 platforms is perfomed while removing the OHCI module from kernel. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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); Signed-off-by:

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 install the modem(ACM) driver based on class-subclass-protocol matching. This patch corrects the protocol code in ACM IAD to the same as in acm_control_interface_desc protocol code. Acked-by:

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 accomplish this the function to register a gadget driver takes the bind function as a second argument. To make things clearer rename the function to resemble platform_driver_probe. This fixes many section mismatches like WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in reference from the variable printer_driver to the function .init.text:printer_bind() The variable printer_driver references the function __init printer_bind() All callers are fixed.

This patch removes string registration from the Mass Storage Gadget. With recent changes to the composite framework, all that we need is handled by the composite layer. This means composite registers a string ID for manufacturer and product.

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. Signed-off-by:
