guvcview shows window "Guvcview error: Unable to open device"

[John Rose]

Window also says "Please make sure the camera is connected
and that the correct driver is installed." Only option given is "Close". This results in guvcview terminating.
PS The device (Celestron usb digital microscope) works OK with Cheese app.

Closing since this concerns version 1.1.3 of Guvcview.

If the problem persists in version 1.5.3, which is default in Ubuntu 12.04, please open a new bug report.

I have the same problem in precise pangolin.

Here us what I see on konsole:

I also got the same error. I added guvcview's repository and installed the latest version. Now nothing happens when I click on the icon. The application does not open at all. I am using Ubuntu 12.04.

Status changed to 'Confirmed' because the bug affects multiple users.
