Problem description: 
Logitech, Inc. Orbicam (ID 046d:0896) doesn't work with Cheese (green led on 
cam doesn't light up and no images appear) unless we run Cheese multiple 
consecutive times. Webcam doesn't work with Skype too (no images and led turned 
off).
This problem has started when Ubuntu 10.10 was installed (kernel 
2.6.35-27-generic - 64 bits). Webcam was working at Ubuntu 10.04 (all kernel 
versions released until Mar-08 / 2011).

Ubuntu version:
Distributor ID: Ubuntu
Description:    Ubuntu 10.10
Release:        10.10
Codename:       maverick

Kernel version:
Linux 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011 x86_64 
GNU/Linux

Steps to reproduce the bug:

(With Cheese)
1. run Cheese - green led on cam doesn't light up and a black screen appears 
instead of the image.
2. close Cheese and start it again.
3. If the cam still doesn't work, repeat step 2.

(With Skype 2.1.0.81)
1. run Skype (/usr/bin/skype-wrapper)
2. Log in as a valid user.
3. At the main menu, click "Options", and then click the "Video" tab on the left
4. Enable Skype Video. Check the box next to "Enable Skype Video."
5. Open the pull-down menu of devices. Select the device (sometimes it appears 
as /dev/video0 and sometimes as /dev/video1).
6. Click at the "Test" webcam button. 
7. Green led on cam doesn't light up and a black screen appears instead of the 
image.

Expected results:
Cam led lights up and image appears when Cheese is started.
Cam led lights up and image appears in the web cam test at Skype.
