Since num is unsigned, it would seem better to use simple_strtoul that simple_strtol. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r2@ long e; position p; @@ e = simple_strtol@p(...) @@ position p != r2.p; type T; T e; @@ e = - simple_strtol@p + simple_strtoul (...) // </smpl> Signed-off-by:

Impact: cleanup Found this when I changed args to __module_param_call. We now have core_param for exactly this, but Greg assures me "nousb" is used as a module parameter, so we need the #ifdef MODULE. Signed-off-by:

This patch (as1175) makes usb-storage set a SCSI device's request-queue bounce limit such that all buffers will be located in addressable memory (i.e., not in high memory) if the host controller's dma_mask is NULL. This is necessary when the host controller doesn't support DMA: If a buffer is in high memory then the both the virtual and DMA addresses produced by the scatter-gather library will be NULL, preventing the HCD from accessing the buffer's data. In particular, the isp1760 driver needs this when used on a system with more than 1 GB of memory. Signed-off-by:

This patch (as1172) adds the ability to emulate a CD-ROM drive to g_file_storage. The emulation is limited, since it presents as a disc containing a single data track and no audio tracks. Still, it may come in useful on occasion. Signed-off-by:

Add a few devices known to have support for larger sense buffers. Supporting SANE_SENSE does not necessarily mean SAT-1 or SAT-2 is fully supported. Depends on SANE_SENSE patch [1]. Incorporates the Maxtor and Western Digital devices originally submitted by Matthieu CASTET [2].

Add the SANE SENSE flag to indicate that a device is capable of handling more than 18-bytes of sense data. This functionality is required for USB-ATA bridges implementing SAT. A future patch will actually enable this function for several devices. The logic behind this is that we can detect support for SANE_SENSE in a few ways: 1) ATA PASS THROUGH (12) or (16) execute successfully 2) SPC-3 or higher is in use 3) A previous CHECK CONDITION occurred with sense format 70-73 and had a length greater than 18-bytes total Signed-off-by: -

This patch (as1166) changes usb_new_device(). Now new devices will be announced in the log _prior_ to being registered; this way the "new device" lines will appear before all the output from driver probing, which seems much more logical. Also, the patch adds a call to usb_stop_pm() to the failure pathway, so that the parent's count of unsuspended children will remain correct if registration fails. In order for this to work properly, the code to increment that count has to be moved forward, before the first point where a failure can occur. Signed-off-by:

usbmon can only be built as a module if usbcore is a module too. Trivial changes to the relevant Kconfig and Makefile (and a few trivial changes elsewhere) allow usbmon to be built as a module even if usbcore is builtin. This is verified to work in all 9 permutations (3 correctly prohibited by Kconfig, 6 build a suitable result). Signed-off-by:

This patch introduces a new call to be able to do a USB reset from an atomic contect. This is quite helpful in USB callbacks to handle errors (when the only thing that can be done is to do a device reset). It is done queuing a work struct that will do the actual reset. The struct is "attached" to an interface so pending requests from an interface are removed when said interface is unbound from the driver. The call flow then becomes: usb_queue_reset_device() __usb_queue_reset_device() [workqueue] usb_reset_device() usb_probe_interface() usb_cancel_queue_reset() [error path] usb_unbind_interface() usb_cancel_queue_reset() usb_driver_release_interface() usb_cancel_queue_reset() Note usb_cancel_queue_reset() needs smarts to try not to unqueue when it is actually being executed. This happens when we run the reset from the workqueue: usb_reset_device() is called and on interface unbind time, usb_cancel_queue_reset() would be called. That would deadlock on cancel_work_sync(). To avoid that, we set (before running usb_reset_device()) usb_intf->reset_running and clear it inmediately after returning. Patch is against 2.6.28-rc2 and depends on http://marc.info/?l=linux-usb&m=122581634925308&w=2 (as submitted by Alan Stern).

This patch (as1163b) adds a "quirks=" module parameter to usb-storage. This will allow people to make short-term changes to their unusual_devs list without rebuilding the entire driver. Testing will become much easier, and less-sophisticated users will be able to access their buggy devices after a simple config-file change instead of having to wait for a new kernel release. The patch also adds a documentation entry for usb-storage's "delay_use" parameter, which has been around for years but but was never listed among the kernel parameters. Signed-off-by:

A published errata for ppc440epx states, that when running Linux with both EHCI and OHCI modules loaded, the EHCI module experiences a fatal error when a high-speed device is connected to the USB2.0, and functions normally if OHCI module is not loaded. There used to be recommendation to use only hi-speed or full-speed devices with specific conditions, when respective module was unloaded. Later, it was observed that ohci suspend is enough to keep things going, and it was turned into workaround, as explained below. Quote from original descriprion: The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB 2.0 Host controllers, each EHCI controller has one or more companion controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will contain one or more ports. For each port, only one of the controllers is connected at any one time. In the 440EPx, there is only one OHCI companion controller, and only one USB 2.0 Host port. All ports on an USB 2.0 controller default to the companion controller. If you load only an ohci driver, it will have control of the ports and any deviceplugged in will operate, although high speed devices will be forced to operate at full speed. When an ehci driver is loaded, it explicitly takes control of the ports. If there is a device connected, and / or every time there is a new device connected, the ehci driver determines if the device is high speed or not. If it is high speed, the driver retains control of the port. If it is not, the driver explicitly gives the companion controller control of the port. The is a software workaround that uses Initial version of the software workaround was posted to linux-usb-devel: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html and later available from amcc.com: http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2 The patch below is generally based on the latter, but reworked to powerpc/of_device USB drivers, and uses a few devicetree inquiries to get rid of (some) hardcoded defines.

This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe. Signed-off-by:

Instead of waiting a painful 5000ms, quirk_usb_disable_ehci() now does a 1000ms loop to wait for the BIOS to acknowledge the handoff. The five second delay is really quite irritating to have to deal with every boot up, and I very seriously doubt any non-broken bios takes more than a second to do the actual handoff. Signed-off-by:
