I have bought some time ago a web camera. The brand is media-tech. I have gnomeDE. When I started cheese it recognizes the web camera and it shows that it is connected but it seems unable to show the capture of the camera. Am I misiing a driver?

there are so many web cameras out there, all with differing chipsets.

sometimes those dont play well with linux, and the symptoms described sound like issues i have seen in the past with

some logitec gsapi cameras.

But with a very generic sounding brand name you have given, its very difficult for anyone who does not have one of these
to make a judgement.

to help us to help you, please run

Code: Select all: su - *root*password**** lsusb and lsmod

from a terminal
and paste them back here in a code block.

with this everyone will have a better chance helping you

can you please install lsusb, (usbutils) and run it again

looking at the usbcore i dont see any video modules loaded

usbcore 228947 5 usb_storage,ehci_hcd,ehci_pci,usbhid,xhci_hcd

so it maybe that this cam is not supported by linux.

lsusb will give us an ID , we are looking for something like 04f2:b330

with that we can see if it is a recognised and supported device.

looking at amazon though if this is the one i think it is, priced at about £20 then I would think again, and highly recommend that you get
a cam based on UVC as these are probably the best supported by linux.

http://www.ideasonboard.org/uvc/#devices

lists all the devices that are UVC

personally I have 3 of these Logitech Quickcam Communicate Deluxe/S7500
and one of these Logitech Quickcam Pro 5000

and both work great.

many cheaper devices, and this does not only apply to webcams, rely on all the hard work being done by a software component
and the hardware actually contains the bear minimum to work.

more expensive devices , and usually higher performance devices, contain much more on board HW .

in the open source world the cheaper ones, software component is only written for windows, by the manufacturer,
and the only way to get it working in linux is if some bright spark reverse engineers it.

the UVC interface is well defined and as a result well supported.

regards peter

I just ordered a Logitech Quickcam Communicate Deluxe/S7500 from amazon based on the recommendation by wintpe. Thanks.
