This should speed up the option driver's upload speed quite a bit. It has been tested by a number of different people on different devices with success. Cc: Roland Wolters <roland.wolters@credativ.de> Signed-off-by:Greg Kroah-Hartman <gregkh@suse.de>

Some of the usb-serial drivers are starting to use urb->status in ways they should not be doing. This fixes up some of them to prevent that. Signed-off-by: -

Contains fixes so probe on x86 PCI runs, apparently I'm first to try this. Several fixes to memory access to probe host scratch register. Previously would bug check on chip_addr var used uninitialized. Scratch reg write failed in one instance due to 16-bit initial access mode, so added "& 0x0000ffff" to the readl as fix. Includes some general cleanup - remove global vars, organize memory map resource use. Signed-off-by:

this driver can't handle (of course) any brdige class devices. So we now are just active on one specific bridge which should be only the isp1761 chip behind a PLX bridge. Signed-off-by:

This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by:

This patch (as1178) uses the new round_jiffies_up_relative() routine for setting the autosuspend delayed_work timer. It's appropriate since we don't care too much about the exact length of the delay, but we don't want it to be too short (rounded down). Signed-off-by:

gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

This moves the isp1301-omap driver from the drivers/i2c/chips directory (which will be shrinking) into a new drivers/usb/otg directory (which will grow, with more drivers and utilities). Note that OTG infrastructure needs to be initialized before either host or peripheral side USB support, and may be needed before for pure host or pure peripheral configurations. Signed-off-by:

Random host-side MUSB updates, mostly relating to better diagnostics: + Improve diagnostics on host side: - tx flush fifo: * Avoid hundreds of duplicate TX FIFONOTEMPTY messages * make "Can't flush TX fifo" a warning, and say which endpoint - giveback: * use correct status code * show completion function name not just URB pointer - Fix annoying "1 bytes" (should be "1 byte") + Be more consistent about failing init of unusable fifo_mode It's not clear why that "can't flush TX fifo" message appears, though it might relate to disconnection; I see it not infrequently Signed-off-by: -

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:

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:

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].

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:
