Webcams

Hello Everyone ! 

I am here to find some  solution to the problem I am facing with my "Quickcam Pro for Notebooks" M/N: V-UBU48.
My general specification of laptop is as under:
-Toshiba Satellite A-205 Pentium Dual CPU T2330 @1.60GHz with 2 gb Ram
-Intel(R) Graphics Media Accelerator (Mobile Intel(R) 965 Express Chipset Family)
- OS: Windows 7 Ultimate 32-bit Service Pack 1 (Regularly update)

Problem:
I have been using my logitech webcam from more then 2 months on this same system. My webcam is attached to my system via Usb hub. But few days back, i have been experiencing a certain problem that arises when i tried to use webcam using skype, windows live messenger or Logitech Vid HD. Whenever  I switch the video on, it started for few seconds and then switches off itself (activity light turns off) with a *sound of unplugging usb device*. I try again, and same happens each time. I have deleted the drivers, cleared the registry and then did a fresh install of latest software and drivers but still problem persists. I tried to check the webcam performance throughe the LWS 2.27 but it does same - switch on and off itself. When its on software shows the name of webcam attached and when its gone, it shows "no webcam attached" and keeps on doing it intermittently. 
I would appreciate anyones effort to root out this problem for me. Waiting for helpful replies.

P.s. My webacam microphone works well even at that time and other person hears me.

My guess is that your webcam needs higher current to operate than the one supplied by your USB hub. This can be easily verified - if you plug the webcam directly into the USB port of the computer, do you still have the problem?

A solution you could try (if you absolutely need to use a USB hub) is to search the market for a USB hub having its own power supply. This will ensure your webcam receives the current it needs to work properly.

So Nice of you sir for the reply. 

I have attached it to a direct USB to my system and its working quite fine now. Well, suprisingly I also see horizontal running  lines on the video. You think that its the same low voltage problem ?

Hello rafistyle:

Thank you for posting your issue to the Logitech Community Forums.

Where you are getting horizontal running lines, it probably has something to do with RightLight. To get rid of this RightLight issue, please do the following:

1) On your desktop click on the Logitech Webcam Software icon

2) Click on QuickCapture

3) Click oon Controls underneath your image

4) At bottom of new Control screen click on Advanced Settings

5) At this screen, the Advanced Settings screen,uncheck RightLight and Auto

6) Bring setting of Exposure as far right as possible

7) Slide gain as far to the left as possible

8) Gradually slide gain to the right until you can see an image clearly and lines should not be present and

9) Save

Hope this helps!

Regards
