            Bug ID: 196323
           Summary: Thinkpad usb keyboard with integrated mouse requires a
                    usb quirk
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: misc
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: jrm at ftfl.ca

I have a Thinkpad keyboard with an integrated mouse like
http://support.lenovo.com/us/en/documents/migr-73183.

# usbconfig -d ugen0.2 dump_device_desc
ugen0.2: <ThinkPad USB Keyboard with TrackPoint Lite-On Technology Corp.> at
usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0110 
  bDeviceClass = 0x0000 
  bDeviceSubClass = 0x0000 
  bDeviceProtocol = 0x0000 
  bMaxPacketSize0 = 0x0008 
  idVendor = 0x17ef 
  idProduct = 0x6009 
  bcdDevice = 0x0127 
  iManufacturer = 0x0001  <Lite-On Technology Corp.>
  iProduct = 0x0002  <ThinkPad USB Keyboard with TrackPoint>
  iSerialNumber = 0x0000  <no string>
  bNumConfigurations = 0x0001 

With a GENERIC kernel, the mouse doesn't work until this quirk:

# usbconfig add_dev_quirk_vplh 0x17ef 0x6009 0x0000 0xffff UQ_HID_IGNORE

The quirk wasn't necessary in the past when I was versions older than 10.

Thanks to frogs in #freebsd on freenode for helping me debug this.
