Webcam trust non funzionante con ubuntu 19.10

Ok grazie mille per tutto. Ho provato a cambiare porta USB ma la webcam trust non si appende proprio. a questo punto ho riesumato una webcam della play station la eye toy che prima non funzionava mentre ora con guvcview funziona bene, mentre con Skype viene riconosciuta ma rimane immagine nera.

ho ricaricato il modulo ed eseguito i comandi richiesti ed ho la seguente risposta:

sergio@sergio-desktop:~$ sudo modprobe gspca_pac207 [sudo] password di sergio: sergio@sergio-desktop:~$ lsmod | grep gspca gspca_pac207 16384 0 gspca_main 24576 1 gspca_pac207 videobuf2_vmalloc 20480 1 gspca_main videobuf2_v4l2 24576 1 gspca_main videobuf2_common 53248 2 gspca_main,videobuf2_v4l2 videodev 208896 4 gspca_main,videobuf2_v4l2,gspca_pac207,videobuf2_common sergio@sergio-desktop:~$ dmesg | grep gspca [ 2482.383802] gspca_main: v2.14.0 registered [ 2482.387709] gspca_main: pac207-2.14.0 probing 093a:2468 [ 2494.185231] gspca_main: pac207-2.14.0 probing 093a:2468 [ 2499.049126] gspca_main: pac207-2.14.0 probing 093a:2468 sergio@sergio-desktop:~$

apro Cheese o guvcview ma nulla di fatto. ho scaricato anche Qt v4l2 test utility

comandi dati ma non succede nulla ho provato a far partire Cheese o guvcview ma senza fortuna: sergio@sergio-desktop:~$ lsmod | grep gspca sergio@sergio-desktop:~$ lsmod | grep gspca sergio@sergio-desktop:~$ lsmod | grep gspca sergio@sergio-desktop:~$ dmesg | grep gspca

per i codec ho la seguente risposta :

sergio@sergio-desktop:~$ dpkg -l | grep codecs ii chromium-codecs-ffmpeg-extra 79.0.3945.79-0ubuntu0.19.10.2 amd64 Transitional package - chromium-codecs-ffmpeg-extra -> chromium-ffmpeg snap ii gstreamer1.0-packagekit 1.1.12-5ubuntu4 amd64 GStreamer plugin to install codecs using PackageKit ii libavcodec58:amd64 7:4.1.4-1build2 amd64 FFmpeg library with de/encoders for audio/video codecs - runtime files ii libopencv-imgcodecs3.2:amd64 3.2.0+dfsg-6 amd64 computer vision Image Codecs library

Ho installato Guvcview ma quando lo avvio mi da errore: No Video device found

Coma altri player ho Cheese e VLC ma nessuno dei due vede la webcam

Fatto, ma c'e' sempre qualcosa che non va :

sergio@sergio-desktop:/dev$ sudo gpasswd -a sergio video [sudo] password di sergio: Aggiunta dell'utente sergio al gruppo video sergio@sergio-desktop:/dev$ sudo modprobe gspca_pac207 sergio@sergio-desktop:/dev$ mplayer tv://dev/video0 MPlayer 1.3.0 (Debian), built with gcc-9 (C) 2000-2016 MPlayer Team do_connect: could not connect to socket connect: No such file or directory Failed to open LIRC support.

con i comandi che mi indichi questa è la risposta da terminale :

sergio@sergio-desktop:~$ cd /dev sergio@sergio-desktop:/dev$ ls|grep video sergio@sergio-desktop:/dev$ groups sergio adm cdrom sudo dip plugdev lpadmin lxd sambashare sergio@sergio-desktop:/dev$

Di seguito la risposta ai comandi che mi hai indicato:

sergio@sergio-desktop:~$ cd /dev sergio@sergio-desktop:/dev$ ls|grep video sergio@sergio-desktop:/dev$ groups sergio adm cdrom sudo dip plugdev lpadmin lxd sambashare sergio@sergio-desktop:/dev$

Con il comando ls -l /dev/video* il risultato è sempre di errore:

sergio@sergio-desktop:~$ dmesg | grep video [ 729.711919] videodev: Linux video capture interface: v2.00 sergio@sergio-desktop:~$ ls -l /dev/video ls: impossibile accedere a '/dev/video': File o directory non esistente sergio@sergio-desktop:~$ ls -l /dev/video ls: impossibile accedere a '/dev/video': File o directory non esistente
