2015-03-07USB: serial: fix infinite wait_until_sent timeoutJohan Hovold1-2/+3
Make sure to handle an infinite timeout (0). Note that wait_until_sent is currently never called with a 0-timeout argument due to a bug in tty_wait_until_sent.

2015-03-03usb: ftdi_sio: Add jtag quirk support for Cyber Cortex AV boardsMax Mansfield2-0/+5
This patch integrates Cyber Cortex AV boards with the existing ftdi_jtag_quirk in order to use serial port 0 with JTAG which is required by the manufacturers' software. Steps: 2 [ftdi_sio_ids.h] 1. Defined the device PID [ftdi_sio.c] 2. Added a macro declaration to the ids array, in order to enable the jtag quirk for the device.

2015-03-02USB: ch341: set tty baud speed according to tty structNicolas PLANEL1-9/+6
The ch341_set_baudrate() function initialize the device baud speed according to the value on priv->baud_rate. By default the ch341_open() set it to a hardcoded value (DEFAULT_BAUD_RATE 9600). Unfortunately, the tty_struct is not initialized with the same default value. (usually 56700) This means that the tty_struct and the device baud rate generator are not synchronized after opening the port. Fixup is done by calling ch341_set_termios() if tty exist. Remove unnecessary variable priv->baud_rate setup as it's already done by ch341_port_probe(). Remove unnecessary call to ch341_set_{handshake,baudrate}() in ch341_open() as there already called in ch341_configure() and ch341_set_termios() Signed-off-by: Nicolas PLANEL <nicolas.planel@enovance.com> Signed-off-by: Johan Hovold <johan@kernel.org>

Add call to __module_get when initialising the fake tty in usb_console_setup to match the module_put in release_one_tty. Note that the tty-driver (i.e. usb-serial core) must be compiled-in to enable the usb console so the __module_get is essentially a noop as driver->owner will be null.

If a USB serial device is unplugged while there is an active program using the device it may spam the logs with -EPROTO (71) messages as it attempts to retry. Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output these messages for debugging. The generic driver treats these as errors.

2014-10-23usb: serial: ftdi_sio: add "bricked" FTDI device PIDPerry Hung2-0/+7
An official recent Windows driver from FTDI detects counterfeit devices and reprograms the internal EEPROM containing the USB PID to 0, effectively bricking the device. Add support for this VID/PID pair to correctly bind the driver on these devices.
