2009-03-24USB: usbmon: Add binary API v1Pete Zaitcev
This patch adds an extension to the binary API so it reaches parity with existing text API (so-called "1u"). The extension delivers additional data, such as ISO descriptors and the interrupt interval. Signed-Off-By: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
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: musb: partial DaVinci dm355 supportDavid Brownell
Partial support for DaVinci DM355, on the EVM board; peripheral mode should work, once mainline merges DM355 support. Missing: (a) renumbering the GPIO for DRVVBUS on the DM6446 EVM, when DAVINCI_N_GPIO increases; (b) disabling DM355_DEEPSLEEP.DRVVBUS_OVERRIDE so VBUS is driven according to the ID signal, if cpu_is_..._dm355() The new PHY control bits are ignored on DM6446.

2009-03-24USB: musb: only turn off vbus in OTG hostsAjay Kumar Gupta
Except on DaVinci, VBUS is now switched off as part of idling the USB link (after a_wait_bcon) whenever a device is disconnected from host. This is correct for OTG hosts, where either SRP or an ID interrupt could turn VBUS on again. However, for non-OTG hosts there's no way to turn VBUS on again, so the host becomes unusable. And the procfs entry which once allowed a manual workaround for this is now gone. This patch adds an is_otg_enabled() check before scheduling the switch-off timer in disconnect path, supporting a "classic host" mode where SRP is unavailable.

Correct musb_read_fifosize() and musb_configure_ep0() functions for the #ifndef BLACKFIN branch when the silicon uses static FIFO configuration.

2009-03-24USB: musb: NAK timeout scheme on bulk RX endpointAjay Kumar Gupta
Fixes endpoint starvation issue when more than one bulk QH is multiplexed on the reserved bulk RX endpoint, which is normal for cases like serial and ethernet adapters. This patch sets the NAK timeout interval for such QHs, and when a timeout triggers the next QH will be scheduled. (This resembles the bulk scheduling done in hardware by EHCI, OHCI, and UHCI.) This scheme doesn't work for devices which are connected to a high to full speed tree (transaction translator) as there is no NAK timeout interrupt from the musb controller from such devices. Tested with PIO, Inventra DMA, CPPI DMA.

2009-03-24USB: musb: rewrite host periodic endpoint allocationSergei Shtylyov
The current MUSB host code doesn't make use of all the available FIFOs in for periodic transfers since it wrongly assumes the RX and TX sides of any given hw_ep always share one FIFO. Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep' to check the endpoint's business; get rid of the now-unused 'periodic' array in the 'struct musb'. Also optimize a loop induction variable in the endpoint lookup code.

2009-03-24usb-storage: make sddr09 a separate moduleAlan Stern
This patch (as1207) converts usb-storage's sddr09 subdriver into a separate module. An unexpected complication arises because of DPCM devices, in which one LUN uses the sddr09 transport and one uses the standard CB transport. Since these devices can be used even when USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h require special treatment. If SDDR09 isn't configured then the entries remain in unusual_devs.h; if it is then the entries are present in unusual_sddr09.h instead.

2009-03-24usb-storage: prepare for subdriver separationAlan Stern
This patch (as1206) is the first step in converting usb-storage's subdrivers into separate modules. It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions.

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 generic resume function fixOliver Neukum
This removes an unnecessary check for autoresume from the generic resume method. The check has been obsoleted by the now delayed increase of the usage counter which makes the error this check prevented impossible. This change allows drivers which only use the bulk read URB the use of the generic method even if they support autosuspend.

That is necessary to let drivers know whether they should report an error back. Signed-off-by: Oliver Neukum <oneukum@suse.de> Hi Greg, this is for 2.6.30. Patches to use this in drivers are under development. Regards Oliver

This patch implements suspend and resume methods for the option driver. With my hardware I can even suspend the system and keep up a connection for a short time.
