Webcam Test Programs
luvcview and guvcview are display programs that can be used to test a webcam. uvccapture will save an image to the current directory. Each were installed with Synaptic. For example to run luvcview:
eepp@tabor:~$ luvcview luvcview 0.2.6 SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 Stream settings: Frame format: MJPG Frame size: 640x480 Frame rate: 30 fps
Trouble Shooting USB
Us lsusb from usbutils. You can check installation with Synaptic. For example:
eepp@tabor:~$ lsusb Bus 004 Device 006: ID 04fe:0006 PFU, Ltd Bus 004 Device 005: ID 04fe:0008 PFU, Ltd Bus 004 Device 003: ID 03eb:21fe Atmel Corp. Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 003: ID 05ac:0304 Apple, Inc. Optical USB Mouse [Mitsumi] Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 010: ID 046d:0805 Logitech, Inc. Bus 001 Device 007: ID 06c2:0059 Phidgets Inc. (formerly GLAB) Bus 001 Device 006: ID 06c2:0045 Phidgets Inc. (formerly GLAB) PhidgetInterface Kit 8-8-8 Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
For example the following will give you a lot of information about the Logitech webcam on bus 1 device 10.
eepp@tabor:~$ lsusb -s 1:10 -v bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 239 Miscellaneous Device bDeviceSubClass 2 ? bDeviceProtocol 1 Interface Association bMaxPacketSize0 64 idVendor 0x046d Logitech, Inc. idProduct 0x0805 ...
