Greetings!
I've been successfully using the webcam "Fujifilm MV-1" with this driver.
Its vendor:productid code is 0461:0821.
It's SPCA533-based, I just copied a new entry from other SPCA533 cameras:
[file gspca_core.c]
...
case 0x0821: /* FUJIFILM MV-1 */
spca50x->desc = FUJIFILMMV1;
spca50x->bridge = BRIDGE_SPCA533;
spca50x->sensor = SENSOR_INTERNAL;
break;
...
I am attaching the full patch.
Have a nice day.
