You could try adding the following line:
qc->vdev.dev = &usbdev->dev;
just before the call to:
r = video_register_device(&qc->vdev, VFL_TYPE_GRABBER, video_nr);
at around line 3160 of the qc-driver.c file in the qc-usb source and recompile
the driver.

if (r<0) goto fail3;
This has the effect of setting the video devices parent device, and then HAL
will create the correct entry:
udi = '/org/freedesktop/Hal/devices/usb_device_46d_840_noserial_video4linux'
info.capabilities = {'video4linux', 'video4linux.video_capture'} (string list)

(string)
info.product = 'Logitech QuickCam USB' (string)
info.subsystem = 'video4linux' (string)
info.udi =
'/org/freedesktop/Hal/devices/usb_device_46d_840_noserial_video4linux' (string)
linux.device_file = '/dev/v4l/video0' (string)
linux.hotplug_type = 2 (0x2) (int)

linux.sysfs_path = '/sys/class/video4linux/video0' (string)
video4linux.device = '/dev/v4l/video0' (string)
