2010-03-02USB: cdc_acm: Silence "It is not a modem." error for pbLua devicesJulian Calaby
The pbLua console port is known to not be a modem, so it is unnecessary to be told this when it is plugged in. Add NOT_A_MODEM quirk to tell the driver that we know this already and hence not to warn us, and mark the pbLua console port.

2010-03-02USB: cdc_acm: Add support for pbLua console portJulian Calaby
The pbLua firmware (http://pblua.com/) for the Lego Mindstorms NXT provides a CDC ACM port for it's serial console. This used to be detected automatically, but this support has been dropped, probably for sensible reasons. Explicitly add support for this device by adding an item to the device ID table.

2010-03-02usbmon: add bus number to text APIPete Zaitcev
Due to a simple oversight when bus zero was added, the text API fails to deliver the bus number in 'E' messages (which are equivalent of 'C' messages, only for error case). This makes it harder, for instance, use a search-and-highlight in a text editor. So fix it. Also, Alan Stern requested adding timestamps to 'E' messages. This is purely cosmetic, but makes it easier to read the trace. This is done for both text and binary APIs.

2010-03-02USB: gadget: use ep5 for bulk-in and ep6 for bulk-out for Blackfin MUSBBryan Wu
Normally, the musb uses ep1 as the bidirectional bulk endpoint. This won't work on the Blackfin musb as all endpoints (except ep0) are unidirectional. Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable for bulk endpoints (which need more like a 512 byte FIFO). This leaves us with ep5-ep7 which have 1024 byte FIFOs and can be configured as either in/out and bulk/interrupt/iso on the fly.

2010-03-02USB: cypress_m8: allow unstable baud ratesMike Frysinger
I've got a crappy cypress converter here, and while running at higher baud rates craps out on throughput, it works fine with lower ones. While it'd be nice to simply use a lower baud rate, not all devices can be configured this way, and it is possible to (slowly) interact at higher rates by sending a byte at a time.

2010-03-02USB: Add call to notify xHC of a device reset.Sarah Sharp
Add a new host controller driver method, reset_device(), that the USB core will use to notify the host of a successful device reset.

2010-03-02USB: xhci: Notify the xHC when a device is reset.Sarah Sharp
When a USB device is reset, the xHCI hardware must know, in order to match the device state and disable all endpoints except control endpoint 0. Issue a Reset Device command after a USB device is successfully reset. Wait on the command to finish, and then cache or free the disabled endpoint rings. There are four different USB device states that the xHCI hardware tracks: - disabled/enabled - device connection has just been detected, - default - the device has been reset and has an address of 0, - addressed - the device has a non-zero address but no configuration has been set, - configured - a set configuration succeeded. The USB core may issue a port reset when a device is in any state, but the Reset Device command will fail for a 0.96 xHC if the device is not in the addressed or configured state. Don't consider this failure as an error, but don't free any endpoint rings if this command fails. A storage driver may request that the USB device be reset during error handling, so use GPF_NOIO instead of GPF_KERNEL while allocating memory for the Reset Device command.

Refactor the code to clear the port change bits in the port status register. All port status change bits are write one to clear.

We read the port after the write to get the updated status for debugging, so the port read after that is unnecessary.

2010-03-02USB: xhci: Refactor test for vendor-specific completion codes.Sarah Sharp

2010-03-02USB: xhci: Allow allocation of commands without input contexts.Sarah Sharp
The xhci_command structure is the basic structure for issuing commands to the xHCI hardware. It contains a struct completion (so that the issuing function can wait on the command), command status, and a input context that is used to pass information to the hardware. Not all commands need the input context, so make it optional to allocate. Allow xhci_free_container_ctx() to be passed a NULL input context, to make freeing the xhci_command structure simple.

2010-03-02USB: xhci: Fix error path when configuring endpoints.Sarah Sharp
If we fail to queue an evaluate context command or a configure endpoint command to the command ring in xhci_configure_endpoint(), we need to remove the xhci_command structure from the device's command list before returning. If the command is left on the command list, it will sit there indefinitely, blocking commands submitted after this fails.

2010-03-02USB: check the endpoint type against the pipe typeAlan Stern
This patch (as1316) adds some error checking to usb_submit_urb(). It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users. The new check makes sure that the actual type of the endpoint described by urb->pipe agrees with the type encoded in the pipe value. The USB error code documentation is updated to include the code returned by the new check, and the usbfs SUBMITURB handler is updated to use the correct pipe type when legacy user code tries to submit a bulk transfer to an interrupt endpoint.
