2014-01-03USB: ch341: fix ignored TIOCMIWAIT maskJohan Hovold
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).

The USB storage operation of Nokia Asha 502 Dual SIM smartphone running Asha Platform 1.1.1 is unreliable in respect of data consistency (i.e. transfered files are corrupted). A similar issue is described here: http://discussions.nokia.com/t5/Asha-and-other-Nokia-Series-30/Nokia-301-USB-transfers-and-corrupted-files/td-p/1974170 The workaround is (MAX_SECTORS_64): rmmod usb_storage && modprobe usb_storage quirks=0421:06aa:m The patch adds the tested device to the unusual list permanently.

2014-01-03USB: serial: add Moxa UPORT 12XX/14XX/16XX driverAndrew Lunn
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.

2014-01-03USB: pl2303: use direct baud-rate encoding when possibleJohan Hovold
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).

2014-01-03USB: pl2303: fix data corruption on termios updatesJohan Hovold
Some PL2303 devices are known to lose bytes if you change serial settings even to the same values as before. Avoid this by comparing the encoded settings with the previsouly used ones before configuring the device. The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode switching regression"), but this problem was still possible to trigger, for instance, by using the TCSETS2-interface to repeatedly request 115201 baud, which gets mapped to 115200 and thus always triggers a settings update.
