* USB: Add OTG PET device to TPLMacpaul Lin2015-02-201-0/+4
| | | | | | | | | | | | | commit e5dff0e80463cc3fa236e898ef1491b40be70b19 upstream. OTG device shall support this device for allowing compliance automated testing.

* usb-core bInterval quirkJames P Michels III2015-02-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | commit cd83ce9e6195aa3ea15ab4db92892802c20df5d0 upstream. This patch adds a usb quirk to support devices with interupt endpoints and bInterval values expressed as microframes. The quirk causes the parse endpoint function to modify the reported bInterval to a standards conforming value. There is currently code in the endpoint parser that checks for bIntervals that are outside of the valid range (1-16 for USB 2+ high speed and super speed interupt endpoints). In this case, the code assumes the bInterval is being reported in 1ms frames. As well, the correction is only applied if the original bInterval value is out of the 1-16 range. With this quirk applied to the device, the bInterval will be accurately adjusted from microframes to an exponent.

* USB: Add device quirk for ASUS T100 Base Station keyboardLu Baolu2014-12-141-0/+4
| | | | | | | | | | | | | | | | | | | | commit ddbe1fca0bcb87ca8c199ea873a456ca8a948567 upstream. This full-speed USB device generates spurious remote wakeup event as soon as USB_DEVICE_REMOTE_WAKEUP feature is set. As the result, Linux can't enter system suspend and S0ix power saving modes once this keyboard is used. This patch tries to introduce USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk. With this quirk set, wakeup capability will be ignored during device configure. This patch could be back-ported to kernels as old as 2.6.39.

The usb device will autoresume from choose_wakeup() if it is autosuspended with the wrong wakeup setting, but below errors occur because usb3503 misc driver will switch to standby mode when suspended.

* usb: Add device quirk for Logitech HD Pro Webcams C920 and C930eJulius Werner2014-04-021-0/+4
| | | | | | | | | | | | | | | | | | commit e0429362ab15c46ea4d64c3f8c9e0933e48a143a upstream. We've encountered a rare issue when enumerating two Logitech webcams after a reboot that doesn't power cycle the USB ports. They are spewing random data (possibly some leftover UVC buffers) on the second (full-sized) Get Configuration request of the enumeration phase. Since the data is random this can potentially cause all kinds of odd behavior, and since it occasionally happens multiple times (after the kernel issues another reset due to the garbled configuration descriptor), it is not always recoverable. Set the USB_DELAY_INIT quirk that seems to work around the issue.

* USB: add RESET_RESUME for webcams shown to be quirkyOliver Neukum2011-09-181-0/+21
| | | | | | | | | | | | | | | The new runtime PM code has shown that many webcams suffer from a race condition that may crash them upon resume. Runtime PM is especially prone to show the problem because it retains power to the cameras at all times. However system suspension may also crash the devices and retain power to the devices. The only way to solve this problem without races is in usbcore with the RESET_RESUME quirk.

* USB: improve uses of usb_mark_last_busyAlan Stern2010-11-161-9/+0
| | | | | | | | | | | | | | | | | | | This patch (as1434) cleans up the uses of usb_mark_last_busy() in usbcore. The function will be called when a device is resumed and whenever a usage count is decremented. A call that was missing from the hub driver is added: A hub is used whenever one of its ports gets suspended (this prevents hubs from suspending immediately after their last child). In addition, the call to disable autosuspend support for new devices by default is moved from usb_detect_quirks() (where it doesn't really belong) into usb_new_device() along with all the other runtime-PM initializations. Finally, an extra pm_runtime_get_noresume() is added to prevent new devices from autosuspending while they are being registered.

* USB: use the runtime-PM autosuspend implementationAlan Stern2010-11-161-6/+0
| | | | | | | | | | | | | This patch (as1428) converts USB over to the new runtime-PM core autosuspend framework. One slightly awkward aspect of the conversion is that USB devices will now have two suspend-delay attributes: the old power/autosuspend file and the new power/autosuspend_delay_ms file. One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

* USB: change handling of negative autosuspend delaysAlan Stern2010-03-021-0/+10
| | | | | | | | | | | | | | | | | This patch (as1327) changes the way negative autosuspend delays prevent device from autosuspending. The current code checks for negative values explicitly in the autosuspend_check() routine. The updated code keeps things from getting that far by using usb_autoresume_device() to increment the usage counter when a negative delay is set, and by using usb_autosuspend_device() to decrement the usage counter when a non-negative delay is set. This complicates the set_autosuspend() attribute method code slightly, but it will reduce the overall power management overhead.

* USB: implement usb_enable_autosuspendAlan Stern2010-03-021-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | This patch (as1326) adds usb_enable_autosuspend() and usb_disable_autosuspend() routines for use by drivers. If a driver knows that its device can handle suspends and resumes correctly, it can enable autosuspend all by itself. This is equivalent to the user writing "auto" to the device's power/level attribute. The implementation differs slightly from what it used to be. Now autosuspend is disabled simply by doing usb_autoresume_device() (to increment the usage counter) and enabled by doing usb_autosuspend_device() (to decrement the usage counter). The set_level() attribute method is updated to use the new routines, and the USB Power-Management documentation is updated. The patch adds a usb_enable_autosuspend() call to the hub driver's probe routine, allowing the special-case code for hubs in quirks.c to be removed.

| | | | | | | | | | | | | | | | | | | This patch (as1052) enables USB-PERSIST for all devices by default. The user won't have to remember to enable it explicitly for devices containing mounted filesystems. Eventually userspace tools like hal may be able to set the persist attribute automatically when a filesystem is mounted on a USB device. When that time comes this patch can be reverted, if people think it matters.

| | | | | | | | | | | | | | | | | | | | This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND quirk. Since autosuspend is disabled by default, we will let userspace worry about which devices can safely be suspended. Thus the lengthy series of quirk entries is no longer needed, and neither is the quirk ID. I suppose someone might eventually run across a hub that can't be suspended; let's ignore the possibility for now. The patch also cleans up the hasty way in which autosuspend gets disabled. Setting udev->autosuspend_delay to -1 wasn't quite right, because the value is always supposed to be a multiple of HZ. It's better to leave the delay value alone and set autosuspend_disabled, which is what the quirk routine used to do.

* USB: disable autosuspend by default for non-hubsAlan Stern2007-09-131-0/+6
| | | | | | | | | | | | This patch (as965) disables autosuspend by default for all USB devices other than hubs. We are seeing too many devices that can't suspend or resume properly, the blacklist is growing unreasonably quickly, and this sort of thing should be handled in userspace.

| | | | | | | | I would like have the attached patch added to Linux kernel. The three usb flash memories listed in the patch are being used in Intel's ClassmatePC and need USB_QUIRK_RESET_RESUME to work reliably when resuming from ram.
* USB: quirky flash driveOliver Neukum2007-09-111-0/+2
| | | | | | | | | That drive is quite odd. It has 2K sectors, times out getting string descriptors and needs a quirk. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

It may not be necessary for all such devices, but the one in Bugzilla #8892 sometimes fails to resume.

* usb quirks: Add Canon EOS 5D (PC Connection mode) to the autosuspend blacklistPaul Walmsley2007-08-221-0/+3
| | | | | | | | | | | | | | | | | | | Recent versions of the Linux kernel auto-suspend attached USB devices. After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints don't seem to wake back up correctly, causing further use with libgphoto2 to fail with a -114 "OS error in camera communication" error. A similar fix is probably necessary for this camera in PTP mode, which identifies as USB product id 0x3102, but we haven't tested this. As part of our testing process, we tried the USB_QUIRK_RESET_RESUME quirk also, it's not helpful in this case.
