最近在用USB摄像头，发现驱动正常加载，插上USB摄像头，内核设备总是无法加载摄像头的驱动，也没有vidoe0设备，但我以前在2410上是可以的。如下：
/ # usb 1-1: new full speed USB device using s1r72v27 and address 2
usb 1-1: Product: PC Camera
usb 1-1: Manufacturer: Z-Star Corp.
usb 1-1: configuration #1 chosen from 1 choice
于是我仔细和2410的Linux2.6.14.1对比了驱动，发现仅仅少选了一个选项，就造成了这个问题！
Device Drivers --->
| Generic Driver Options --->
<*> Userspace firmware loading support
选上后重新编译就可以了
/ # usb 1-1: new full speed USB device using s1r72v27 and address 2
usb 1-1: Product: PC Camera
usb 1-1: Manufacturer: Z-Star Corp.
usb 1-1: configuration #1 chosen from 1 choice
drivers/usb/media/gspcav1/gspca_core.c: USB GSPCA camera found.(ZC3XX)
