HSDPA调制解调器仅在某些USB端口上工作

Question

根据我用来连接HSDPA调制解调器的USB端口，网络管理器将连接到internet或不连接internet。我以前在所有端口上工作(即自动建立互联网连接)，但随着时间的推移，它只是在一些端口上停止工作。

在所有情况下，lsusb输出都是这样的(设备ID取决于USB端口)：

Bus 001 Device 009: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem

有什么想法可以导致这种行为？我能做些什么来解决这个问题？

已添加

有关调制解调器的一个附加信息:如果通过USB连接，它将作为硬盘和HSDPA调制解调器(某种双重性.)提供。在错误情况下，它将只显示为硬盘。

Answer 1

给定输出，我们可以在这里假设如下：

• 这与硬件故障无关。
• 该调制解调器有一个虚拟光盘与Windows驱动程序，这些是无用的，只有在这里烦人。
• ubuntu modemmanager包是专门为处理这些问题而设计的(例如，禁止安装假光盘)，并且有一个越来越多的调制解调器和服务提供商数据库。如果他们已经拥有你的，请参阅维基，如果没有，如何添加它。
• 不应该需要手工制作的文本，如wvdial.conf或99-udev-huawei-rules.conf概述的这里，它应该是开箱即用的。
• 它很可能是一个bug，一个缺失的条目，或者两者兼而有之。它甚至可能已经修复了，所以您可以尝试一个模式管理器/网络管理器PPA，或者测试它是否与一个活动CD一起工作，从而获得一些成功。
• 如果你向供应商要一种老式的调制解调器(如果它与你的合同捆绑在一起，这个计划可以持续六个月以上，商店的销售人员足够聪明，可以把退货的调制解调器放在抽屉里，你可以说出它的名字)，你甚至可以立即获得成功。

Answer 2

在Windows7对我的E156G (黑色"3“意大利3G互联网供应商)，我注意到，它的工作只注意到一个USB集线器，可能是一个通信问题，集线器过滤。WMWare Windows虚拟化端口上的扫描器驱动程序也出现了类似的解决方案。

两个驱动程序与USB集线器识别，原来的拨号程序可以在Windows 7上正常工作，但只有一个驱动程序可以直接插入USB笔记本端口，设备也不能完全识别，拨号程序也不能识别硬件。没有出现第二个驱动程序。所以，试着在设备之间使用USB集线器。

我的USB集线器是targus透明蓝色的(Targus的Ultra Mini USB2.0 4-端口集线器)。

Answer 3

您需要做的是确保当您连接时，它处于正确的模式。也就是说，它应该被认为是调制解调器，而不是光盘。有几种方法可以实现这一点，一种是确定光盘的id，通常是sr*，其中*可以是某个数字。你需要用

sudo eject /dev/sr1

用查看dmesg的相关标识符替换1。

你可以使用usb模式自动为你做这件事。如果我没有弄错的话，它可以在ubuntu回购中找到。链接在这里

[Dialer cdma]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Baud = 115200
SetVolume = 0
;       New PPPD = yes
Modem = /dev/ttyUSB0
Dial Command = ATDT
 Phone = #777
 Password = mts
 Username = internet@internet.mtsindia.in
/etc/wvdial.conf (END)

这是我的wvdial.conf，您需要根据您使用的载体和位置更改用户名和密码。

是的，当调制解调器工作时，它既是存储设备，也是调制解调器。
