我有一台运行 Debian Jessie 64 位的 Dell Inspiron 5547（500 系列）。
我的 lsusb 输出是：
Bus 001 Device 004: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 003: ID 8087:07dc Intel Corp.
Bus 001 Device 002: ID 8087:8000 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
我的dmesg | grep 'video'输出是：
[ 6.138288] Linux video capture interface: v2.00
[ 6.240522] usbcore: registered new interface driver uvcvideo
我已经安装了 v4l 并加载了 uvcvideo 模块但是，Cheese 说“找不到设备视频”。
更新1
ls -l /dev/video*（文件o目录不存在）。
ls: no se puede acceder a /dev/video*: No existe el fichero o el directorio
我尝试以 root 身份运行 Cheese，但结果相同。
更完整的 dmesg 输出：

有任何想法吗 ？
