求教:我在qq2440v3上使用usb摄像头(中星微芯片),如果我从nand flash启动后,插入摄像头,显示:
usb 1-1: new full speed USB device using s3c2410-ohci and address 2
usb 1-1: device descriptor read/64, error -110
usb 1-1: device descriptor read/64, error -110

usb 1-1: new full speed USB device using s3c2410-ohci and address 5
usb 1-1: device not accepting address 5, error -110
/dev下没有生成v4l目录。摄像头无法使用。
但如果我从nor flash进去后用
Boot the system 启动内核后插入摄像头完全正常。
板上烧的内核为arm123上下载的《qq2440-linux-images-20070706》,zImage_s35 + root_qtopia_mouse.img。
在qq2440群里提问过,没人搭理,恳求来往高人指教!
