Hi,

I recently bought an HP Pavillion DV3 laptop that has an integrated webcam.
After searching a while I found out that the webcam is an UVC webcam but it
isn't on the list of supported cams.

This is the usb entry of lsusb:
Bus 002 Device 004: ID 174f:1118 Syntek


I added the usb vendor + product id to the driver like this:
        /* Syntek (HP Pavillion dv3) */
        { .match_flags          = USB_DEVICE_ID_MATCH_DEVICE
                                | USB_DEVICE_ID_MATCH_INT_INFO,
          .idVendor             = 0x174f,
          .idProduct            = 0x1118,
          .bInterfaceClass      = USB_CLASS_VIDEO,
          .bInterfaceSubClass   = 1,
          .bInterfaceProtocol   = 0,
          .driver_info          = UVC_QUIRK_STREAM_NO_FID },


The device is recognized by the driver:
uvcvideo: Found UVC 1.00 device HP Webcam (174f:1118)


Now I have a problem. When I try to use it, the "in use" led from the camera
lights up, but software doesn't receive any image (stays black all the
time).
Here is my dmesg:
uvcvideo: Failed to resubmit video URB (-1).
uvcvideo: Trying format 0x56595559 (YUYV): 640x480.
uvcvideo: Using default frame interval 41666.6 us (24.0 fps).
uvcvideo: Setting frame interval to 1/24 (416666).
uvcvideo: Trying format 0x56595559 (YUYV): 640x480.
^^ This last 2 lines repeat themself several times (the first one has got my
attention but I don't know what's the problem)

Attached is a log of "guvcview" program starting and closing. After it
starts, it starts printing the errors:
 Could not grab image (select timeout): Resource temporarily unavailable
 Could not grab image (select timeout): Resource temporarily unavailable
 Could not grab image (select timeout): Resource temporarily unavailable
 Could not grab image (select timeout): Resource temporarily unavailable
 Could not grab image (select timeout): Resource temporarily unavailable


Any pointers on how can I help getting this camera supported on the driver?
