Hans, I have several questions: - The fact it's a USB 1.0 device, can it be a problem? - When plugged, /dev/usb/0.3.0 is created and linked to /dev/ugen0.3. /dev/usb/0.3.1 is also created. I assume it's Endpoint 1, but I don't have any /dev/ugen0.3.1 is it normal? - If I try to read data from /dev/usb/0.3.1, I get kernel: ugen_isoc_read_callback: actlen=0, aframes=0 syslogd: last message repeated 1 times kernel: ugen0.3: <vendor 0x05a9 product 0xa511> at usbus0 (disconnected) For that, I quickly updated old vid program (http://ovtvid-bsd.sourceforge.net/) used on 4.11 for 12.1 (see https://people.freebsd.org/~blackend/usb/vid.c). I get the same behavoir as with webcamd, i.e., all configuration settings via the control endpoint are accepted, once the program tries to get video data it fails (the device is disconnected). -- Marc
