Logitech C270 не имеет видеовыхода Ubuntu 18.04 - proUbuntu

/ 22 апреля 2020

Моя веб-камера Logitech C270 без перерыва r работает на моем рабочем столе, предположительно, после r и обновляется до Ubuntu 18.04.

Я перечислил некоторые из моих системных сведений и журналов ниже. Кто-нибудь может дать какой-нибудь совет? Спасибо!

Информация о системе

Работает Ubuntu 18.04 LTS.

Информация о ядре:

$ uname -r
4.15.0-88-lowlatency

Существует только одно видеоустройство:

$ ls /dev/video*
/dev/video0

Обнаружена веб-камера:

$ lsusb | grep Logitech
Bus 003 Device 007: ID 046d:0825 Logitech, Inc. Webcam C270
$ sudo lshw | grep Logitech -B3 -A6
*-usb:2       
   description: Video
   product: Webcam C270
   vendor: Logitech, Inc.
   physical id: 9
   bus info: usb@3:9
   version: 0.12
   serial: E4E41130
   capabilities: usb-2.00
   configuration: driver=snd-usb-audio maxpower=500mA speed=480Mbit/s

В настоящее время веб-камера подключена к порту USB 2.0, поскольку, как я видел, источники говорят, что она не работает с USB 3.0 .

Попытка использовать веб-камеру

Я пытался использовать guvcview и cheese; оба, похоже, пытаются использовать веб-камеру (на /dev/video0), поскольку на веб-камере включается зеленый свет, но отсутствует видеовыход.

Запуск guvcview не показывает видеовыход и печатает следующие журналы:

dmesg вывод, показывающий, что я в конце пробовал разные порты USB:
