* USB: ftdi_sio: remove unnecessary initialisationsJohan Hovold2010-03-02
| | | | | | | | | | | | Return values are being initialised to zero only to be unconditionally assigned to a few instructions later. This may give the impression that zero is returned on success, which is not the case. Note also that ftdi_NDI_device_setup never reports errors.

* USB: retain USB device power/wakeup setting across reconfigurationDan Streetman2010-03-02
| | | | | | | | | | | | | | | | | | | | | | Currently a non-root-hub USB device's wakeup settings are initialized when the device is set to a configured state using device_init_wakeup(), but this is not correct as wakeup is split into "capable" (can_wakeup) and "enabled" (should_wakeup). The settings should be initialized instead in the device initialization (usb_new_device) with the "capable" setting disabled and the "enabled" setting enabled. The "capable" setting should be set based on the device being configured or unconfigured, and "enabled" setting set based on the sysfs power/wakeup control. This patch retains the sysfs power/wakeup setting of a non-root-hub USB device over a USB device re-configuration, which can happen (for example) after a suspend/resume cycle.

* USB: cdc_acm: Silence "It is not a modem." error for pbLua devicesJulian Calaby2010-03-02
| | | | | | | | | | | | | The pbLua console port is known to not be a modem, so it is unnecessary to be told this when it is plugged in.

* usbmon: add bus number to text APIPete Zaitcev2010-03-02
| | | | | | | | | | | | | | | | | 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.

* USB: gadget: use ep5 for bulk-in and ep6 for bulk-out for Blackfin MUSBBryan Wu2010-03-02
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.

* USB: xhci: Notify the xHC when a device is reset.Sarah Sharp2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
