E680i使用usb联接线联接到Linux机器上以后，使用lsusb可以看到联接的设备

Bus 001 Device 006: ID 22b8:3802 Motorola PCS C330/A780 GSM Phone Bus 001 Device 003: ID 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam Bus 001 Device 001: ID 0000:0000 Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000

现在使用ifconfig也无法看到usb0这一设备。需要在E680i运行acmattach.txt，内容如下：

echo MotNet > /proc/motusbd

然后运行ifconfig -a可以看到usb0设备

blueice:~# ifconfig -a eth0      Link encap:Ethernet  HWaddr 00:50:8D:D1:64:4C           inet addr:192.168.1.210  Bcast:192.168.0.255  Mask:255.255.255.0           inet6 addr: fe80::250:8dff:fed1:644c/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:515 errors:0 dropped:0 overruns:0 frame:0           TX packets:184 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:69421 (67.7 KiB)  TX bytes:18637 (18.2 KiB)           Interrupt:177 Base address:0xb000 lo        Link encap:Local Loopback           inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:16436  Metric:1           RX packets:17035 errors:0 dropped:0 overruns:0 frame:0           TX packets:17035 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:20847754 (19.8 MiB)  TX bytes:20847754 (19.8 MiB) sit0      Link encap:IPv6-in-IPv4           NOARP  MTU:1480  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) usb0      Link encap:Ethernet  HWaddr E6:CA:62:C6:3F:4C           BROADCAST MULTICAST  MTU:1500  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

为usb0设备配置ip地址后可以telnet到E680i

此时在Linux主机上查看usb设备显示如下

blueice:/lib/modules# lsusb Bus 003 Device 001: ID 0000:0000 Bus 004 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 005: ID 22b8:600c Motorola PCS A768i GSM Phone Bus 001 Device 001: ID 0000:0000 Bus 001 Device 003: ID 0ac8:301b Z-Star Microelectronics Corp.

E680i的设备号也有变化
