USBSer="USB Serial Driver"                                      ; String value for the USBSer symbol

重点是安装前通过搜索将mdmcpq.inf及USBser.sys从c:/windows/winsxs/?????????等目录中找出，

分别将mdmcpq.inf拷贝到c:/windows/inf,USBser.sys拷贝到c:/windows/system32/drivers目录，将

atm6124_cdc.inf拷贝到c:/windows/inf,然后对拷贝目标目录下的驱动程序文件进行修改。

atm6124_cdc.inf该驱动文件会自动导入mdmcpq.inf驱动，mdmcpq.inf中需要Copy USBser.sys文件，安装出错是因为该文件无法找到，具体原因还不清楚，解决方法如下。

atm6124_cdc.inf文件将下成三行

[USBtoSer.Install] ; Install section
include=mdmcpq.inf
CopyFiles=FakeModemCopyFileSection

改为

[USBtoSer.Install] ; Install section
include=mdmcpq.inf
;CopyFiles=FakeModemCopyFileSection

或者

修改mdmcpq.inf文件将

USBser.sys,,,0x20

改为

;USBser.sys,,,0x20
