I bought a Raspberry Pi camera (https://www.raspberrypi.org/products/camera-module/) and it works great.
My problem is that there's no way to build a good-looking device with that camera. I've seen camera cases but the wire is uncovered and it's ugly (If anybody knows a good-looking, cheap solution, nice ... but my question here is about other cameras)
So I've been working with standard USB cameras.
I've done a complete update/upgrade:
sudo rpi-update sudo apt-get update sudo apt-get upgrade
I've change some params as other forums suggested, to change config.txt and add
and check gpu_mem is above 128 (mine is 256)
But when I plug the camera (and the camera works because I've tested in PC computers) and I try to access it, it does not work:
pi@raspberrypi ~ $ raspistill -o /tmp/a.jpg mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM) mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1) mmal: Failed to create camera component mmal: main: Failed to create camera component mmal: Camera is not detected. Please check carefully the camera module is installed correctly
the camera is not detected
pi@raspberrypi ~ $ vcgencmd get_camera supported=1 detected=0
but it's there !

I've tried also unplugging the raspberry Pi camera on board, and leave just my USB camera, changing settings in raspi-config of board camera to on and off ...
Also I've tried with 4 different USB cameras (all working in PC's) ... Trust, Logitech, ...
Question 1: what is the problem ?
In a page says: "Is your power supply sufficient? The camera adds about 200-250mA to the power requirements of your Raspberry Pi."
Question 2 : How can I measure this ? How can I know what is my power (I got a B+), and how much power each one of the USB ports are consuming ?
