不需要加载kernel模块的linux dnw

这个不需要加载内核模块，省去了编译内核模块的麻烦，不过需要libusb的支持，安装libusb和libusb-dev这两个包就可以了，详见包里面的README
我在qq2440上测了下，烧写kernel时下载速度有250 KB/s，应该比较快了。

# ./dnw2 /home/farce/u-boot.bin

这个是怎么回事啊？

以下显示的应该是USB设备了，我的是6410，是不是源码需要改一下？

找到原因了，6410的EP 2 OUT是0x02而源码中是03，还是下载另一个专用的吧http://www.aiothome.net/read.php?fid=59&tid=14235&u=30116
