我有一台英特尔 N3450 迷你笔记本电脑。
网络摄像头在 Windows 10 下作为“Intel AVStream”摄像头运行，安装 ubuntu 23.04 后无法识别网络摄像头。我还尝试了 Fedora 和 Manjaro 的 live iso，但没有成功。Skype/Discord/Cheese 等应用程序找不到任何网络摄像头设备。
这是我的笔记本电脑的 USB 硬件列表：

我猜这个多媒体控制器可能是集成的网络摄像头设备？因为它在lspci -v输出中显示 [disabled]：
00:03.0 Multimedia controller: Intel Corporation Celeron N3350/Pentium N4200/Atom E3900 Series Imaging Unit (rev 0b)
Flags: fast devsel, IRQ 21
Memory at 90000000 (64-bit, non-prefetchable) [disabled] [size=16M]
Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
Capabilities: [ac] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [d0] Power Management version 3
但我现在很迷茫。我该如何解决无法正常工作的网络摄像头？请指教。
