USB Devices

Webcams

Overview

The Gumstix Mailing List received an email from mbelge with some great information about USB cameras that were tested at different resolutions.

The tests were done using a Tobi Expansion Board powered by an Overo FireSTORM COM running on Steve Sakoman's GNOME Linux Image. Both the USB Host port and USB OTG port were used in the tests, the latter by way of a powered Belkin USB hub (USB ID: 05e3:0608). MPlayer was the capture utility, using the following command:

$ mplayer tv:// -tv device=/dev/video7:width=<width>:height=<height>

Table of Working Webcams

Make	Model	USB ID	Achieved resolutions on Tobi via		Notes
			USB Host	USB OTG
Gigaware	25157 Webcam with Microphone	093a:2700	With artifacts: 160x120 176x144 352x288 640x480	None	Only worked via USB Host. All resolutions had artifacts on the captured image in the form of horizontal lines. Mplayer sometimes reported "frame too small?" Erratic enumeration, sometimes failing, sometimes enumerated as video7 and other times as video0
Gigaware	25177 1.3 MP Webcam with Microphone	0c45:62e0	640x480 800x600 With artifacts: 160x120 176x144 352x288 640x480	Intermittently: 160x120 176x144 320x240	USB OTG works at up to 320x240 for a while with no artifacts. MPlayer later reports "input/output error" and the streaming stops
Logitech	C210	046d:819	640x480 With artifacts: 160x120 175x144 320x240	None	USB OTG showed select timeouts and garbled image at all resolutions
Logitech	HD Webcam C310	046d:0816	640x480 With artifacts: 160x120 175x144 320x240	160x120 176x144 Intermittently: 320x240	Does not work in MPlayer at all initially, reporting an initialization error and failing to display images. Starting Cheese, a webcam application, seemed to initialize the camera and switching back to MPlayer subsequently worked USB OTG: Resolutions including and above 320x240 reported select timeouts and had garbled image. The video stream stops after a couple of minutes, while higher resolutions fail immediately.
Logitech	Webcam C600	046d:0808	640x480 800x600 With artifacts: 160x120 175x144 320x240	160x120 175x144	Resolutions including and above 320x240 reported select timeout errors Resolutions including and above 640x480 did not work at all

Device Enumeration

All cameras consistently enumerated as video7, except the Gigaware 25157 Webcam with Microphone, which demonstrated erratic enumeration, sometimes enumerated as video7, sometimes as video0 and other times failing altogether.

IEEE 1394/FireWire Devices with USB Connectivity

Point Grey Cameras

Point Grey Cameras with USB can be connected to a Gumstix Overo configuration using libdc1394 (an API for IEEE1394 / Firewire cameras) and OpenCV, for example. The camera used in this particular test was the FireFly MV. Libdc1394 is available on the project page and can be easily compiled.
