我有一个 Creative VF0640 网络摄像头，它原本可以在较旧的 Linux 系统上运行，但在 OpenSuSE Leap 15.1 (x86_64) 机器上无法运行。连接摄像头时内核似乎可以识别它，但 uvcvideo 表示没有设备存在：

No devices found.
不用说，我的前端应用程序（guvcview-qt5 和 kamoso）都找不到摄像头。我甚至找不到设备文件：
╭─jacek@epica ~
╰─➤ ls -al /dev/vid*
zsh: no matches found: /dev/vid*
这是我的内核版本：
╭─jacek@epica ~
╰─➤ uname -a 1 ↵

这里出了什么问题？谢谢。
