2014-10-23usb: serial: ftdi_sio: add "bricked" FTDI device PIDPerry Hung
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.

2014-09-15USB: serial: remove zte_ev driverJohan Hovold
The zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Lei Liu, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1) let's remove the redundant zte_ev driver. Also move the remaining ZTE PIDs to the generic option modem driver. Reported-by: Lei Liu <liu.lei78@zte.com.cn> Signed-off-by: Johan Hovold <johan@kernel.org>

2014-09-01USB: sierra: avoid CDC class functions on "68A3" devicesBjørn Mork
Sierra Wireless Direct IP devices using the 68A3 product ID can be configured for modes including a CDC ECM class function. The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist.

2014-08-18Revert "USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"Johan Hovold
This reverts commit 73228a0538a7 ("USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"). Move the IDs of the devices that were previously driven by the option driver back to that driver. As several users have reported, the zte_ev driver is causing random disconnects as well as reconnect failures. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Liu Lei, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Note that the zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1), this is a first step in ultimately removing the redundant zte_ev driver. Note that AC2726 had already been moved back to option, and that some IDs were in the device table of both drivers prior to the commit being reverted.
