| * USB: serial: fix stalled writesJohan Hovold2010-08-101-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As David VomLehn points out, it was possible to receive an interrupt before clearing the free-urb flag which could lead to the urb being incorrectly marked as busy. For the same reason, move tx_bytes accounting so that it will never be negative. Note that the free-flags set and clear operations do not need any additional locking as they are manipulated while USB_SERIAL_WRITE_BUSY is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add a US Interface, Inc. "Navigator" USB device. Specifically, it's a HAM Radio USB sound modem that also incorporates three pairs of unique FTDI serial ports. The standard Linux FTDI serial driver will only recognize the first two serial ports of an unknown FDTI derived device and this patch adds in recognition to these specific new IDs.

| * USB: option: add huawei k3765 k4505 devices to work properlyAndrew Bird2010-08-101-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband usb modems to option.c. It also adds a quirk to the option probe function so that binding to the device's network interface(class 0xff) is avoided. This is necessary to allow another driver to bind to that, and to avoid programs like wvdial opening a nonfunctioning tty during modem discovery.

| * USB: serial: enabling support for Segway RMP in ftdi_sioJohn G. Rogers2010-08-102-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have added the ProductID=0xe729 VendorID=FTDI_VID=0x0403 which will enable support for the Segway Robotic Mobility Platform (RMP200) in the ftdi_sio kernel module. Currently, users of the Segway RMP200 must use a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a udev rule to get the ftdi_sio module to handle the usb interface and mount it on /dev/ttyXXX. This is not a good solution because some users will have multiple USB to Serial converters which will use the ftdi_sio module.

| * USB-BKL: Remove BKL use for usb serial driver probingAndi Kleen2010-08-101-16/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usb serial driver initialization tried to use the BKL to stop driver modules from unloading, but that didn't work anyways. There was already some code to do proper try_module_get, but it was conditional on having a new probe interface. I checked all the low level drivers and they all have proper .owner = THIS_MODULE, so it's ok to always use. The other problem was the usb_serial_driver_list needing protection by a lock. This was broken anyways because unregister did not necessarily have the BKL. I extended the extending table_lock mutex to protect this case too. With these changes the BKL can be removed here.

| * USB: ftdi_sio: fix DTR/RTS line modesDaniel Mack2010-06-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Call set_mctrl() and clear_mctrl() according to the flow control mode selected. This makes serial communication for FT232 connected devices work when CRTSCTS is not set. This fixes a regression introduced by 4175f3e31 ("tty_port: If we are opened non blocking we still need to raise the carrier"). This patch calls the low-level driver's dtr_rts() function which consequently sets TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in cflags, however, does not reset these bits, and so data is not actually sent out on the serial wire.
