2014-03-12USB: serial: continue to write on errorsJohan Hovold1-10/+19
Do not discard buffered data and make sure to try to resubmit the write urbs on errors. Currently a recoverable error would lead to more data than necessary being dropped.

2014-03-12USB: serial: continue to read on errorsJohan Hovold1-4/+17
Make sure to try to resubmit the read urb on errors. Currently a recoverable error would lead to reduced throughput as only one urb will be used until the port is closed and reopened (or resumed or unthrottled).

Drivers are allowed to override the default bulk-out buffer size (endpoint maximum packet size) in order to increase throughput, but it does not make much sense to allow buffers smaller than the default.

2014-01-11usb: core: allow a reference device for new_idWolfram Sang1-1/+3

2014-01-08USB: ftdi_sio: added CS5 quirk for broken smartcard readersColin Leitner1-2/+15
Genuine FTDI chips support only CS7/8. A previous fix in commit 8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE setting") enforced this limitation and reported it back to userspace. However, certain types of smartcard readers depend on specific driver behaviour that requests 0 data bits (not 5) to change into a different operating mode if CS5 has been set. This patch reenables this behaviour for all FTDI devices. Tagged to be added to stable, because it affects a lot of users of embedded systems which rely on these readers to work properly.

2014-01-04USB: ch341: fix ignored TIOCMIWAIT maskJohan Hovold1-8/+4
Make sure the TIOCMIWAIT mask is always honoured. The CH341 interrupt status has a multiple-status changed flag which indicates that multiple status changes has occurred since last interrupt event. Unfortunately, if the final status is the same, there appears to be no way to determine which signal(s) has changed (an even number of times). This means that the multiple-status flag should not be used in TIOCMIWAIT as it leads to the signal mask argument being ignored (e.g. TIOCMIWAIT could return if DSR changes twice, even though the user only cares about carrier changes).

2014-01-04USB: serial: add Moxa UPORT 12XX/14XX/16XX driverAndrew Lunn3-0/+1424
Add a driver which supports the following Moxa USB to serial converters: * 2 ports : UPort 1250, UPort 1250I * 4 ports : UPort 1410, UPort 1450, UPort 1450I * 8 ports : UPort 1610-8, UPort 1650-8 * 16 ports : UPort 1610-16, UPort 1650-16 The UPORT devices don't directly fit the USB serial model. USB serial assumes a bulk in/out endpoint pair per serial port. Thus a dual port USB serial device is expected to have two bulk in/out pairs. The Moxa UPORT only has one pair for data transfer and places a header on each transfer over the endpoint indicating for which port the transfer relates to. There is a second endpoint pair for events, such as modem control lines changing state, setting baud rates etc. Again, a multiplexing header is used on these endpoints. Some ports need to have a kfifo explicitly allocated since the framework does not allocate one if there is no associated endpoints. The framework will however free it on unload of the module. All data transfers are made on port0, yet the locks are taken on PortN. urb->context points to PortN, even though the URB is for port0. Where possible, code from the generic driver is called. However mxuport_process_read_urb_data() is mostly a cut/paste of usb_serial_generic_process_read_urb(). The driver will attempt to load firmware from userspace and compare the available version and the running version. If the available version is newer, it will be download into RAM of the device and started. This is optional and the driver appears to work O.K. with older firmware in the devices ROM. This driver is based on the MOXA driver and retains MOXAs copyright.

2014-01-04USB: pl2303: use direct baud-rate encoding when possibleJohan Hovold1-8/+13
Use direct baud-rate encoding rather than divisors for supported baud rates. This restores the way baud rates were set prior to commit 8d48fdf689fe ("USB: PL2303: correctly handle baudrates above 115200") which added divisor encoding, but also switched to the new encoding method for all baudrates above 115200. As noted by Frank Schäfer <fschaefer.oss@googlemail.com>, baud rate 500k was later errounously added to the supported baud-rate table although it can only be set using divisors. Note that the current implementation could easily be extended to support arbitrary non-standard baud rates using divisors (e.g. by falling back to divisors when the table lookup fails).
