    Looking at the manual for that laptop the webcam is a Motion Eye and it should just work because the driver was integrated into the Linux Kernel. ( http://popies.net/meye/)

    Have you tried an application? Something like Cheese?

    You are missing a critical file - usb.ids. This is the secret decoder ring or Rosetta Stone for lsusb. You can get it here: http://www.linux-usb.org/usb-ids.html

    Once that is installed, things will be much clearer for you.

    i do have cheese ... the problem is that it is dark, so dark you can hardly see anything on it even with all the lights on and curtains open ... it was not like that with windows, it worked well

    ok, got the file, where do i put it, or how do i install it ... sorry i am so dumb with this, but windows made me that way ... i do not have the folder for usbutils to put it into

    Have you tried adjusting the brightness in Cheese?

    It belongs in /var/lib/usbutils/

    It will probably be the only thing in there, and you may have to make the directory.

    yes i did adjust the brightness, it only made it "whiter" did not help the cam pick up more ... and it looks super bad like the first webcam i ever had ... this cam had a nice picture in windows, and all other video looks better with linux, but this cam looks bad ... and grumpy, i tried to male the folder for it, but i either dont know how, or it wouldnt let me ... ill keep trying though

    got the folder placed ... ran lsusb ... gave me the same info as first post, but it didnt say "cannot open "/var/lib/usbutils/usb.ids", No such file or directory"
    all i get when i use lsusb -v is ... Couldn't open device, some information will be missing ... maybe i just need to re-install Linux ... i get errors every day anyway

    Well, look. remove the device, run lsusb, without any parameters, but capture the ouptut:
    Code:
    lsusb > ~/without
    Then plug the device back in, and run lsusb again:
    Code:
    lsusb > ~/with
    Then compare the two files. The "with" file should have one more line than the "without" file. That should be your device, and should give you the device's manufacturer and product ID.

    Sounds like something's messed up with your usb-utils stuff, also.

    i would have to take the laptop apart for that ... may try that on my day off

    GrumpyOldMan Guest

    Well, never mind then. I just looked in the usb.ids file - it's just a text file.

    Device 05ca:18b3 is a Ricoh Co. "Sony Vaio Integrated Webcam"

    What you are [probably] going to want is the r5u870 driver for Ricoh Webcams.

    Googling 05ca:18b3 will give you some starting points.
