Detect usb device shutdown and ignore failed urbs. This happens when the driver is unloaded or the device is unplugged. I'm not sure what other urb statuses should be ignored, and the warning message doesn't need to be shown when the module is unloaded or the device is removed. Signed-off-by:

Use the new ohci-pci quirk infrastructure to address the problem it was created to address: a quirk specific to the Portege 4000, in buzilla as http://bugzilla.kernel.org/show_bug.cgi?id=6723 Also fix a misuse of "__devinit" for the quirk functions. It must not be used without first ensuring that the references from the quirk tables are gone, and that the function using those quirk tables is also gone. Signed-off-by:

Update "usbnet" so that ethtool reports the name of the minidriver in use (e.g. asix, cdc_ether, dm9601, rndis_host) instead of "usbnet". This is a better match to how other network drivers work, resolving a minor open issue. Signed-off-by:

Cleanups to the rndis_host code, and a tweak that helps talking to PXA hardware. Mostly from Ole André Vadla Ravnås <oleavr@gmail.com> - Prevent SET_INTERFACE requests, they give PXA hardware bad indigestion - For paranoia, null a pointer after freeing its data - Wrap up ActiveSync oddities for RNDIS_QUERY in one routine - Use that wrapper when getting the Ethernet address - Whitespace fixes Plus add a comment noting the open issues about some RNDIS clients still needing TBD kinds of browbeating to accept non-jumbogram packets.

Add the "bus zero" feature to the usbmon. If a user process specifies bus with number zero, it receives events from all buses. This is useful when we wish to see initial enumeration when a bus is created, typically after a modprobe. Until now, an application had to loop until a new bus could be open, then start capturing on it. This procedure was cumbersome and could lose initial events. Also, often it's too bothersome to find exactly to which bus a specific device is attached. Paolo Albeni provided the original concept implementation. I added the handling of "bus->monitored" flag and generally fixed it up. Signed-off-by:

Some host controller drivers may need a PIO fallback when a DMA channel is temporarily unavailable. This patch provides an address that such drivers can use for PIO in those cases, and nulls that field out when no such address is available (highmem) which should help usbmon. Signed-off-by:

This patch (as877) adds a "last_busy" field to struct usb_device, for use by the autosuspend framework. Now if an autosuspend call comes at a time when the device isn't busy but hasn't yet been idle for long enough, the timer can be set to exactly the desired value. And we will be ready to handle things like HID drivers, which can't maintain a useful usage count and must rely on the time-of-last-use to decide when to autosuspend. The patch also makes some related minor improvements: Move the calls to the autosuspend condition-checking routine into usb_suspend_both(), which is the only place where it really matters. If the autosuspend timer is already running, don't stop and restart it. Replace immediate returns with gotos so that the optional debugging ouput won't be bypassed. If autoresume is disabled but the device is already awake, don't return an error for an autoresume call. Don't try to autoresume a device if it isn't suspended. (Yes, this undercuts the previous change -- so sue me.) Don't duplicate existing code in the autosuspend work routine. Fix the kerneldoc in usb_autopm_put_interface(): If an autoresume call fails, the usage counter is left unchanged. Signed-off-by:

omninet kills all URBs in close. However write() returns as soon as the URB has been submitted. Killing the last URB means a race that can lose that date written in the last call to write(). As a fix this is moved to shutdown(). Signed-off-by:

This patch adds the USB ID of the ADS Tech USBX-707 USB IR blaster (that comes with the ADS Tech PTV-305 grabber card), which has a ftdi232bm inside hooked up to a pic. With this it should be fairly straightforward to make at least lirc receiving work with this device. I will submit a patch to lirc for that as soon as I have one ready, I'm getting data with minicom with this patch, but need to figure out some more details such as best/correct baudrate.

o The "real" usb-devices export now a device node which can populate /dev/bus/usb. o The usb_device class is optional now and can be disabled in the kernel config. Major/minor of the "real" devices and class devices are the same. o The environment of the usb-device event contains DEVNUM and BUSNUM to help udev and get rid of the ugly udev rule we need for the class devices. o The usb-devices and usb-interfaces share the same bus, so I used the new "struct device_type" to let these devices identify themselves. This also removes the current logic of using a magic platform-pointer. The name of the device_type is also added to the environment which makes it easier to distinguish the different kinds of devices on the same subsystem. It looks like this: add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 ACTION=add DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1 SUBSYSTEM=usb SEQNUM=1533 MAJOR=189 MINOR=131 DEVTYPE=usb_device PRODUCT=46d/c03e/2000 TYPE=0/0/0 BUSNUM=002 DEVNUM=004 This udev rule works as a replacement for usb_device class devices: SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \ NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644" Updated patch, which needs the device_type patches in Greg's tree. I also got a bugzilla assigned for this. :) https://bugzilla.novell.com/show_bug.cgi?id=250659Signed-off-by:Kay Sievers <kay.sievers@vrfy.org> Signed-off-by:

the sierra driver does not directly use usb_kill_urb(). It uses a wrapper. This wrapper means that callbacks which are running are not killed during close, resubmitting and illicitly pushing data into the tty layer. The whole purpose of usb_kill_urb() is subverted. The wrapper must be removed. The same problem as the option driver. Signed-off-by:
