如何在核心中包含 qcserial 模組？
我需要一個編譯的核心，具有 qcserial 模組以支持華為 EM 680 型號（Gobi 3000）。我得到了核心 3.11.6 並且可以在其中找到適當的源文件，
./drivers/usb/serial/qcserial.c但我如何確保它被靜態編譯和載入？我在核心配置對話框中找不到它……有什麼想法嗎？我正在為 arm AT91 CPU 交叉編譯這個核心，我需要對上述單元調製解調器的支持……
“從 linux-3.1.1-1 開始，設備被 qcserial 模組檢測到”——我在https://wiki.archlinux.org/index.php/Gobi_Broadband_Modems上找到了
編輯調製解調器管理器
安裝調製解調器管理器後，我嘗試啟動它，但我並沒有真正得到任何東西，請參閱下面的螢幕輸出：

如果您查看
drivers/usb/serial/Makefile，您會發現CONFIG_USB_SERIAL_QUALCOMM該驅動程序負責。執行
make menuconfig並轉到“設備驅動程序”->“USB 支持”->“USB 串列轉換器支持”->“USB Qualcomm 串列調製解調器”
