It is possible to create devices like /dev/video0, using /sbin/MAKEDEV , to interact with drivers in the kernel. It is likely that you are using a USB webcam. Check if USB is supported (it probably is). Check if the chipset of the webcam is supported and perform an /sbin/insmod of the relevant module as suggested below. You can perform a modprobe to check if any new modules are required and lsmod to check which are currently loaded. > 0. Take a look at the output of dmesg.

If supported then load the corresponding kernel module (it should do > it automatically).
