我尝试在 ARM 板（Pandaboard）上运行 Asus xtion，并且我已经安装并使用了 openni 提供的示例（例如 NiSimpleRead）。为了让这些示例在这个平台上运行，需要进行一些调整，其中之一是将 UsbInterface 手动设置为同步（在 GlobalDefaults.ini 中）。但在那之后一切顺利

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 尝试自行设置 USB 接口（它可能使用 XnUSBLinux.cpp 通用）并尝试绕过 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设备的 USB 接口选项设置为全局同步？或者我如何更改 XnUSBLinux.cpp 以使其运行。

这是 lsusb -v 的输出（简化为华硕设备部分）并显示了两个操作选项（批量和同步）

在如何手动设置一个选项方面获得您的帮助会很棒。
