Has anyone activated the Thinkpad t61 internal usb camera?
This site http://www.linux-usb.org/ibmcam/ lists several vendor ID's
for Chicony Electronics Co., Ltd., but not the vendor ID of this camera.

Different manufacturer, different driver. IBM just rebrands stuff from different manufacturers, and I can't figure out which model of Chicony webcam this corresponds to. The ibmcam driver is for Xirlink-based devices. It is a UVC cam, however, so try the generic media-video/linux-uvc driver.

Thank you! That driver seems to work.
I installed the media-video/linux-uvc driver and loaded the driver.
emerge linux-uvc
echo 'uvcvideo' >> /etc/modules.autoload.d/kernel-2.6
update-modules
modprobe uvcvideo
Here is more info about the camera.

N: v4l/video0
S: video0
E: IN_HOTPLUG=1 |
udevinfo -a -p /class/video4linux/video0
| Code: | Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I installed Ekiga, set it to use v4l2, and when I activated the camera the green light turned on and I can see my self. Yay!
I found the advice from http://forums.gentoo.org/viewtopic-t-429502-highlight-v4lconf+dga.html
Now I need to find applications that will work with it.
Apps that haven't worked: webcam, xawtv, gtkam, and mplayer.
But, I asked to get this camera working, and it does.
Marking as solved |

Ekiga works with this cam.
www.ekiga.org, also known as gnome meeting.
Make sure you used V4L2, and I have a working vid cam.
though quality is pretty shabby, not sure if it's a linux thing or the camera overall

I got mplayer working on a thinkpad t61 (i think its the same cam) with this command:
mplayer -tv driver=v4l2:width=320:height=240:device=/dev/video0 -fps 25 tv://
Been working on this for a week! Now to get the fingerprint scanner going... |
