有没有好方法传输文件到mini2440

我的开发板是mini2440 256M
能正常启动linux，将U盘插到USB Host，开发板怎么访问不了U盘呢？是否有更好的方式将文件传输到开发板？
我是新手，还望高手指点一二，下面是系统启动的信息:

使用 cd /udisk 还是访问不了U盘，插到SD卡插槽用 cd /sdcard 也不行。
只能用串口通过超级终端传送文件，不过串口真的太慢了，才十几K每秒。有没有高人支支招啊？
使用FTP或NFS传输是直接使用交叉的网线与电脑相连吗？用过的说下吧，谢谢啦。

手册均有说明

手册说得太模糊啦，很多地方都漏掉一些步骤。（至少在最新的手册（2013-5-17）上我是没有看到这些步骤，旧版的手册有没有我是不清楚了。虽然后来经过百度知道了，但真的走了很多弯路，新手真不懂这些，希望能改进。）
1、在安装fedora 9的时候仅勾选FTP Server和Legacy Network Server这两个软件是不够的，在执行cp config_ mini2440_t35 .config之后的make menuconfig 这一步会出错。
2、在使用ftp 传送文件方面，仅说明软件方面的操作，硬件如何连接及设置未说明。FTP文件存放的根目录也未说明，不知道见文件放到哪个目录才能传送到开发板。

最好的方式是通过NFS，映射到开发板
