Ich habe hier eine nagelneue USB Dokumentenkamera. Beim anstecken gibt
dmesg

und in lsusb
1 2 3 | ... Bus 001 Device 015: ID 1bcf:28c4 Sunplus Innovation Technology Inc. USB Camera ... |
In Cheese wird die Kamera in der Auswahl angezeigt, aber es kommt kein Bild.
In VLC ist etwas zu sehen (sogar scharf und so ) aber es gibt eine enorme Verzögerung wenn sich im Bild etwas bewegt . VLC schmeißt auch einen Fehler in dmesg
1 | [Mo Feb 7 21:42:20 2022] uvcvideo: Failed to query (GET_CUR) UVC control 2 on unit 2: -110 (exp. 2). |
Ideen?
