OK335xS内核裁剪后不识别USB
根据OK335xS-Linux用户手册V1.0.pdf，对linux-3.2.0进行了内核编译，生成uImage。将该文件拷贝到SD卡，从SD卡启动开发板后，插上U盘，不识别。试了好多方法也没有成功。
查看了开发板启动信息，与正常的启动信息相比，缺少以下信息：
……
usb 1-1: New USB device found, idVendor=0424, idProduct=2514
usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
……
hub 1-1:1.0: USB hub found
hub 1-1:1.0: 4 ports detected
……
这对应着应该在内核中哪些选项啊？
ps：linux-3.2.0的源码是用户光盘(A)里面的。在内核中支持USB设备的选项都选上了。。。 1、试试我们提供的镜像USB接口是否有效
2、对于裁剪内核，您都裁剪了哪些？

1、试试我们提供的镜像USB接口是否有效
2、对于裁剪内核，您都裁剪了哪些？
拷贝 src 目录下的 linux -3.2.0 -forlinx.tar.bz2 文件到 /home/forlinx/work 下面，然后执行以下命令。
1. 解压
tar xvf linux -3.2.0 -forlinx.tar.bz2
cd linux -3.2.0
2. 编译
cp arch/arm/configs/ok335xs_evm_linux_de fconfig .config
make CROSS_COMPILE=arm -arago -linux -gnueabi - ARCH=arm uImage
编译完成后会自动在 arch/arm/boot/ 目录形成 uImage 文件 ,将该文件拷入 SD 卡 boot 分区使用。
我重新按照上面的操作进行，结果插上U盘后，fdisk -l 没有找到我的U盘。
对于内核裁剪，我只是添加了内核中关于iptables的state、string匹配的选项，其他没有修改。 飞凌-unix 发表于 2014-10-30 10:24 static/image/common/back.gif

以上，是开发板启动信息。。。 最后就这么不了了之呢？！ 还有一个问题，
在make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm uImage后会出现选项，
从网上找到答案，make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm menuconfig后再执行以上指令，就不会出现选项。
但是，使用make menuconfig和make CROSS_COMPILE=arm-arago-linux-gnueabi- ARCH=arm menuconfig出现的内核选项不相同，这又是为什么呢？ 本帖最后由 dzlhappy123 于 2014-11-18 15:21 编辑
在编译uImage时必须出现上图所示的选项，然后选择n，再编译之后，生成的uImage就可以支持USB。
这一步感觉是选择板子型号，但是，为什么有时会不出现这一步直接编译成功了呢？（当然，直接编译的不支持USB设备）
这对操作系统会有要求吗？
