由于需要一个具有两个网卡的嵌入式设备，正好手头有一块MINI2440，但只配有一个网卡，所以网上淘了一个ASIX的USB转RJ45的外接网卡，
http://item.taobao.com/item.htm?id=8464327724 然后从官网上下了一个2.6.38的驱动（该驱动声称支持2.6.14--2.6.38的内核），驱动见附件，里面的Makefile-ori是原始的Makefile,包里的Makefile是我修改后的（驱动中我只修改了Makefile）。mini2440是原配的LINUX系统，2.6.32内核。
AX88772B_772A_760_772_178_LINUX_Driver_v4.1.0_Source.zip (38 K) 下载次数:9 make之后一切正常，生成一个asix.ko，然后用ftp上传到mini2440的目录里之后，直接insmod asix.ko 后 显示：
usbcore: registered new interface driver asix
插上USB转RJ45后显示：
[root@FriendlyARM plg]# insmod asix.ko
usbcore: registered new interface driver asix

然后我ifconfig查看了一下：
eth0 Link encap:Ethernet HWaddr 08:90:90:90:90:90

然后我用命令行配置了一下eth1的IP和掩码后，ifconfig了一下：
[root@FriendlyARM plg]# ifconfig eth1 192.168.1.231 netmask 255.255.255.0

我的主机的网络配置：

但是。。。。。我的mini2440和主机相互PING不通啊。。。
互相Ping失败之后，用arp -n查看，发现相互都学习到了对方的IP，但是就是PING不通，为什么呢？求大牛啊，内牛满面。。。求大牛求大牛，大家帮我看看可能是哪一部出错了？？
ps:USB转RJ45的设备很正常，在PC机上能正常工作。
