我使用的是 Debian 10：
4.19.0-8-amd64 #1 SMP Debian 4.19.98-1 (2020-01-26) x86_64 GNU/Linux
在安装 Discord 和 Zoom 之前，网络摄像头工作正常。之后就不再检测到了。有时会在 dmesg 中看到：
[11771.092506] usb 1-1.5: new high-speed USB device number 8 using ehci-pci

我将此行添加到 /etc/defaults/grub 中：
GRUB_CMDLINE_LINUX_DEFAULT="usbcore.autosuspend=-1 quiet"
但没有运气。如有任何建议，将不胜感激。
