新安装了centos6.2，要使用一个usb网卡，但是插上后没有反映，执行lsusb如下：
[root@pangu dm9601]# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 004: ID 0fe6:9700 Kontron (Industrial Computer Source / ICS Advent) DM9601 Fast Ethernet Adapter
Bus 003 Device 003: ID 04b3:3025 IBM Corp. NetVista Full Width Keyboard
Bus 005 Device 002: ID 1d57:0008 Xenta

可以看到网卡的ID为0fe6:9700，
