USB3XIMEA摄像头xiQ:在Ubuntu中安装软件包时出错

Question

我最近买了一台XIMEA xiQ USB 3摄像头。它在Windows中正常工作，但是当我尝试在Ubuntu中使用它时，我得到了如下错误，尽管我遵循了这些指示出现在西美网站上。

老问题，但我实际上是在类似的环境中设置这个问题。Linux在USB上有默认的内存缓冲区限制，它们必须被移除才能工作。

此命令暂时取消限制，因此在API内容之前在终端中运行它：

echo 0 | sudo tee/sys/module/usbcore/parameters/usbfs_memory_mb

这是API在Linux上安装时发出的警告。
