取決於哪個USB連接埠我用來連接我的HSDPA 數據機，網路管理器將連接或不連接網路。我曾經在所有連接埠上工作（即自動建立網路連線），但隨著時間的推移，它只是在某些連接埠上停止。
lsusb所有情況下的輸出如下所示（裝置 ID 會根據 USB 連接埠而變更）：
Bus 001 Device 009: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem
有什麼想法可能導致這種行為嗎？我可以做什麼來解決這個問題？
添加
有關調製解調器的另一項資訊：如果透過 USB 連接，它將作為硬碟使用和作為 HSDPA 數據機（有點二元性...）。在錯誤情況下，它只會顯示為硬碟。
根據要求提供更多信息

答案1
給定輸出，我們可以假設如下：
- 這與硬體故障無關。
- 數據機有一個帶有 Windows 驅動程式的虛擬 CD-ROM，這些驅動程式在這裡毫無用處，而且只會令人煩惱。
- ubuntu modemmanager 軟體包專門用於處理這些問題（例如禁止安裝假 CD-ROM），並且擁有不斷增長的數據機和服務提供者資料庫。看維基百科如果他們已經有你的，以及如果沒有的話如何添加。
- 不需要像
wvdial.conf或99-udev-huawei-rules.conf概述那樣手工製作文本這裡，它應該開箱即用。 - 這很可能是一個錯誤、缺少條目或兩者兼而有之。它甚至可能已經被修復了，所以你可以透過嘗試調製解調器管理器/網路管理器 PPA 或測試它是否可以在具有 Live CD 的 oneiric 中工作來取得一些成功。
- 如果您向提供者索取較舊版本的調製解調器，您甚至可能會立即獲得成功（如果它與您的合約捆綁在一起，則該計劃的有效期超過六個月，並且商店的銷售人員足夠聰明，可以將退回的調變解調器保留在原處）。
答案2
在我的 E156G（黑色「3」三個義大利 3G 網路供應商）的 Windows 7 中，我注意到它只能連接到 USB HUB，可能是 HUB 過濾的通訊問題。透過 WMWare Windows XP 虛擬化連接埠的掃描器驅動程式也有類似的解決方案。
USB HUB 可以識別兩個驅動程序，原始撥號器在Windows 7 上工作正常，但如果我將其直接插入USB 筆記本端口，則只能使用一個驅動程序，並且設備無法完全識別，撥號器也無法識別硬件。第二個司機沒有出現。所以，設備之間盡量使用USB HUB。
我的 USB 集線器是一款 targus 半透明藍色集線器（Targus 的超迷你 USB 2.0 4 連接埠集線器）。
答案3
您的數據機應該可以在任何 USB 上工作，但硬碟通常無法在筆記型電腦上工作，因為並非所有 USB 都是相同的（有些 USB 不供電 - 或者可能不足以支援硬碟）。在我的筆記本上，我有 2 個 USB 和 1 個 USB+firewire，無法透過外部電源供電的硬碟只能在 USB+firewire 上工作。帶有 PSU 的硬碟可在所有 USB 中運作。
答案4
您需要做的是確保連接時處於正確的模式。也就是說，它應該被識別為調製解調器而不是光碟。有幾種方法可以實現此目的，一種是確定光碟的 ID，通常是 sr*，其中 * 可以是某個數字。您需要使用將其彈出
sudo eject /dev/sr1
將 1 替換為您查看 dmesg 的相關識別碼。
您可以使用 usb-modeswitch 自動為您完成此操作。如果我沒記錯的話，它可以在 ubuntu 儲存庫中找到。 連結在這裡
編輯：
[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 = [email protected]
/etc/wvdial.conf (END)
這是我的 wvdial.conf，您需要根據您使用的運營商和您所在的位置更改使用者名稱和密碼。
是的，當調製解調器工作時，它會被檢測為儲存設備和數據機。
