我正在尝试在带有 openwrt 环境的 qemu 中使用加密狗 3G。加密狗参考：华为-K4605。

首先，我在 option.c 中有补丁内核源代码：

我还将内核模块安装为 kmod-usb-serial-option 或 kmod-usb-uhci。接下来，我在 /etc/usb_modeswitch.conf 中禁用了主机上的自动 usb_modeswitch。

我的加密狗有两个产品/供应商 ID，当我们在存储模块中使用它时为 12d1:14c1，在加密狗 3G 模块中使用它时为 12d1:14c6。我使用 usb 选项运行我的 qemu： 

-usb -usbdevice host:12d1:14c6 -usbdevice host:12d1:14c1

我在存储模块中使用 lsusb 在我的 qemu 机器上检测到我的设备。现在我必须切换它：/usr/bin/usb_modeswitch -v 12d1 -p 14c1 -W -M "55534243123456780000000000000011062000000100000000000000000000"

此步骤不起作用。在 usb_modeswitch.c 中放入一些调试代码后，我可以看到 usb_bulk_write 正在工作，但 usb_bulk_read 没有响应。我修改了 usb_modeswitch 的来源，以消除 usb_bulk_read 的无限等待。由于这个修改，我可以通过 lsusb 看到我的加密狗成功切换，但开发条目 ttyUSB0 不是在 /dev 中创建...

usb_modeswitch 的跟踪是：

root@OpenWrt:~# /usr/bin/usb_modeswitch -v 12d1 -p 14c1 -W -M "55534243123456780000000000000011062000000100000000000000000000"

有人有解决方案吗？我是否必须以某种方式配置 qemu 才能通过批量端点将 msg 发送到我的加密狗？

谢谢，
