2009-03-24USB: Fix cp2101 USB serial device driver termios functions for console useVomLehn
This is really a follow up to the modifications Alan Cox made for commit 95da310e66ee8090119596c70ca8432e57f9a97f to pass a tty_struct to various interface functions, which broke the serial configuration (termios) functions when the device is being used as a console. These changes restore the configuration to proper functioning both as a tty and as a console. As Alan notes in that commit, these changes will need to be tweaked when we have a proper console abstraction.

2009-03-24USB: ipaq: handle 4 endpoint devicesMark Ellis
The ipaq driver currently enforces one port on all devices. This is correct for 2 and 3 endpoint devices, but with 4 endpoint devices meaningful communication occurs on the second pair.

2009-03-24USB: CP2101 Support AN205 baud ratesCraig Shelley
This patch adds support for the extended range of baud rates supported by CP2102 and CP2103 devices described in SiLabs AN205. An additional function cp2101_quantise_baudrate rounds the baud rate as per AN205 Table 1. A modification to the baud rate calculation removes a rounding error, allowing the full range of baud rates to be used.

2009-03-24USB: make actual_length in struct urb field u32Greg Kroah-Hartman
actual_length should also be a u32 and not a signed value. This patch changes this field to be 'u32' to prevent any potential negative conversion and comparison errors. This triggered a few compiler warning messages when these fields were being used with the min macro, so they have also been fixed up in this patch.

2009-03-24USB: ch341 serial: fix port number changed after resumeMing Lei
This patch fixes the following bug: .plug ch341 usb serial port into a hub port; .ch341 driver bound to the device and /dev/ttyUSB0 comes .open /dev/ttyUSB0 by minicom and we can use the serial successfully .suspend the ch341 usb serial device(such as: echo suspend > power/level) .resume the ch341 usb serial device (such as: echo on > power/level) .new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists, but is no longer usable by minicom The patch adds suspend and resume callback to ch341 usb driver to prevent it from unbinding during suspend. The /dev/ttyUSB0 is not released until being closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is no longer usable by minicom. It is really a mess for a minicom user. This patch also adds the reset_resume callback to make it usable after resuming from STR or hibernation, for generally STR or hibernation will make the vbus of root-hub lost. Finally enable the driver's supports_autosuspend, for the device is in working order with it. Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-03-24usb-serial: fix usb_serial_register bug when boot with nousb paramDave Young
With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it. Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-03-24USB: serial: refuse to open recently removed USB Serial devicesJames Woodcock
A USB-serial converter device is plugged into a system, and a process opens it's device node. If the device is physically removed whilst the process still has its device node open, then other processes can sucessfully open the now non-existent device's node. I would expect that open() on a device that has been physically removed should return ENODEV. This is manifesting itself with getty on my system. I do the following: 1. set up inittab to spawn getty on ttyUSB0, eg: T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100 2. Plug in USB-serial converter cable 3. Wait for a login prompt on a terminal program attached to the serial cable 4. Login 5. Pull the USB-serial converter cable from the box 6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0 can still be opened. 7. Re-insert the USB-serial converter cable 8. You should no longer get a login prompt over the serial cable, as the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is trying to talk to /dev/ttyUSB0. The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return ENODEV after the USB-serial converter has been pulled. The patch was created against 2.6.28.1. I can supply it against something else if needs be. It is fairly simple, so should be OK. I am using a pl2303 device, although I don't think that makes any difference.

2009-03-24USB: serial: remove recourse to generic methodOliver Neukum
This removes the fallback to the generic method. It is cleaner to explicitely request it. Introducing this was my mistake.

2009-03-24USB: serial generic resume function fixOliver Neukum
This removes an unnecessary check for autoresume from the generic resume method.

2009-03-24USB: drivers: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
