我一直在尝试在 arm9 主板上连接 3g 调制解调器。bot 调制解调器未被检测到。这是我的 lsusb：
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 004: ID 12d1:14fe Huawei Technologies Co., Ltd.
我的 dmesg 给出了类似的信息：
scsi 5:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 2
sr0: scsi-1 drive
scsi 6:0:0:0: Direct-Access HUAWEI SD Storage 2.31 PQ: 0 ANSI: 2

我已经为 arm 安装了 usb_modeswitch。当我运行 usb modeswitch 命令时：usb_modeswitch -c /etc/usb_modeswitch.conf -v 0x12d1 -p 0x14fe -W

因此当我再次运行 lsusb 命令时：

usb 被检测为大容量存储器，但并未被检测为调制解调器。

我需要为 usb_modeswitch 编写任何规则吗？我的 /lib/udev 中没有规则文件，但 /etc/udev/rules.d 中有一些文件。
为什么我的 3g 加密狗被检测为大容量存储而不是调制解调器？我还需要做什么？请尽快帮助我。

首先插入 usb_wan.ko、option.ko、async.ko。在 /lib/udev/rules.d 中写入 40-usb_modeswitch.rules，然后运行 modeswitch。对于 wvdial 配置，这个网站对我有帮助 http://www.sisalik.ee/janek/wp/arhiiv/223
