NetworkManager电信无线上网卡断开联网后需重新插一次网卡才能连接。。。。

[湘黛钗]

如题，设备是华为EC189。首次插入EC189，Ubuntu10.10的NetworkManager就能直接识别，连华为的linux驱动都不用装，
配置自动发现China Telecom Connection，然后点击可连接。
这点比较好（10.04还要usb-modswitch + wvdial 拨号）。


问题是每次插入设备，第一次联网断开后就不能再次重连，只有拔
下来再插一次网卡才行。注销都不管用。


请问是配置问题吗？有没有人遇到类似的问题，郁闷啊。。。。。


求高手帮解决！

第一次插上：dmesg |grep ttyUSB
[ 11.604562] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[ 11.604751] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB1
[ 11.604930] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2

联网后：dmesg |grep ttyUSB
[ 11.604562] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[ 11.604751] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB1
[ 11.604930] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2

断网后：dmesg |grep ttyUSB
[ 11.604562] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[ 11.604751] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB1
[ 11.604930] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2

拔下网卡重插再次：dmesg |grep ttyUSB
[ 11.604562] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[ 11.604751] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB1
[ 11.604930] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2
[ 519.280804] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0
[ 519.280916] option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1
[ 519.281013] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2
[ 530.284754] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0

[ 530.292868] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2

可见networkmanager手动断开连接后没有释放。。。。。
连usb_modeswitch也不能配置了：
sudo usb_modeswitch -W

* usb_modeswitch: handle USB devices with multiple modes

* Version 1.1.4 (C) Josua Dietze 2010

* Based on libusb0 (0.1.12 and above)
