  • 9ac39f28b   USB: add asynchronous autosuspend/autoresume support ... Browse Code »

    This patch (as1160b) adds support routines for asynchronous autosuspend
    and autoresume, with accompanying documentation updates. There
    already are several potential users of this interface, and others are
    likely to arise as autosuspend support becomes more widespread.

  • d4f373e57   USB: usb-storage: add "quirks=" module parameter ... Browse Code »

    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.

  • 796bcae73   USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3] ... Browse Code »

    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.

  • cd40c4c45   USB: fsl_qe_udc: Check for muram allocation errors ... Browse Code »

    The QE UDC doesn't check for cpm_muram_alloc() return values, this
    might cause all sorts of misbehaviour when cpm_muram_alloc() failed
    to allocate the muram memory.

    While at at, change few dev_dbg() calls to dev_err(), so that the
    driver would not die silently.

  • 011b15df4   USB: change interface to usb_lock_device_for_reset() ... Browse Code »

    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.

  • 857cc4dfb   USB: usbtmc: indent & braces disagree, something else is desired ... Browse Code »

    It seems that there's rather involved way to say something
    which is commonly written in a plain simple form.

    Some type changes would probably be necessary to get gcc
    to do bitops instead of divide but it's no worse after my
    change than before I think.

  • ff8973d94   USB: Remove restrictions on signal numbers in devio.c ... Browse Code »

    Just over a year ago (!) I had this brief exchange with Alan Stern:

    >> It seems that the signal that can be used with USBDEVFS_DISCSIGNAL and
    >> in usbdevfs_urb.signr is limited to the real-time signals SIGRTMIN to
    >> SIGRTMAX. What's the rationale for this restriction? I believe that a

    >> problem with the non-real-time signals that I should be aware of.
    >
    > I don't know of any reason for this restriction.

    Since no-one else could think of a reason either, I offer the following
    patch which allows any signal to be used with USBDEVFS_DISCSIGNAL and
    usbdevfs_urb.signr.

  • d859bffc6   USB: EHCI pci-quirks.c: don't wait so long for BIOS handoff ... Browse Code »

    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.
