Sensoray 2251 Linux Ver.X - Manual (Page 4)

After the 2250 has been connected, a /dev/videoN device will be added by the driver,
where N is the next available video device. The ALSA audio device id will appear
under the ALSA device subsystem under /proc/asound. If OSS emulation is enabled,
a /dev/dspN audio device will also appear.
For the 314/614 devices, after the kernel module has been loaded, two video device
entries should appear. The first /dev/videoX device will be the uncompressed capture
device, and the /dev/videoY device will the be compressed capture device.
Troubleshooting
If no video device appears after plugging in the 2250, check the kernel log to verify the
driver has been loaded properly. The dmesg command will print the most recent
kernel messages. For a working 2250, it should appear like this.
Enter s2250loader_probe 2.6 kernel

If the expected kernel output does not appear, use the “lsmod” command to verify the
kernel modules “go7007” “go7007_usb” and “s2250” are loaded. If not loaded, the
“modprobe” command with the name of the missing module may be able to load them
and initialize the device.
