手动为设备设置USB传输类型

Question

我尝试在ARM Board（Pandaboard）上运行Asus xtion，我已经安装并使用了openni提供的样本（例如NiSimpleRead）。要在这个平台上运行这些示例，需要进行一些调整，其中一个是手动将UsbInterface设置为等时（在GlobalDefaults.ini中）。但之后一切顺利

现在我想使用PCL（基于openni）来抓取一些帧，但PCL不起作用。我相信pcl试图自己设置USB接口（它可能使用XnUSBLinux.cpp是通用的）并试图绕过GlobalDefaults.ini，分别不使用我手动设置的USB接口。

我的问题是我是否可以将USB接口的选项设置为设备的等时全局？或者我如何更改XnUSBLinux.cpp以使其运行。

这是lsusb -v的输出（缩减为asus设备部分）并显示两个操作选项（批量和等时）
