usb摄像头驱动移植问题

linuxway.w

插上usb摄像头后： 摄像头z-star芯片组，采用spca5xx驱动
/ # hub.c: USB new device connect on bus1/1/4, assigned device number 3
spca5xx/spca5xx.c:  Devices not found !!
usb.c: USB device 3 (vend/prod 0xac8/0x3330) is not claimed by any active driver.

linuxway.w

我查看了spca5xx源码，原来没有我的3330的product号，修改后
现在出现这种错误
/ # hub.c: USB new device connect on bus1/1/2, assigned device number 3
spca5xx/spca5xx.c: USB SPCA5XX camera found. Type Vimicro Zc302
