USB Camera Glasses are not Recognized

Thu Nov 17, 2016 11:23 pm

So, I bought these camera glasses from Alibaba: Camera Glasses

The problem is that I tried capturing an image with them with no result.
The output of

Code: Select all

fswebcam
is:

When I execute

Code: Select all

lsusb
, it successfully detects the usb device, as can be seen here:

I tried finding more info about the usb device with

Code: Select all

dmesg | less
and the result is that it does recognize it correctly:

Image

I also tried executing

Code: Select all

lsmod
, but I'm not sure which one is the one I need.

I tried googling "Syntek Semiconductor" for possible drivers, but there were none available for Linux, each of those that I found were for Windows.

I continued searching for a solution on the web and I tried multiple forums (including this one) and already implemented every possible advice I could find, but nothing has helped so far.

Can you give me an idea on how to solve this issue? Has anybody had some similar problem with some usb/webcam?

Thanks in advance,
Bojan

Most USB webcams comply to the USB Video Class (UVC) spec, and will use the uvcvideo driver. Your camera appears not to be identifying itself as that.

Use "lsusb -v" to list out the full USB descriptor for the device.

Hey, thanks for the answer. But, that's exactly my problem. The uvcvideo driver not recognizing my camera. Is there some workaround you can think of? Can I somehow FORCE the driver to read the camera? Is there any other general driver used for other, more specific cameras? If not, do you know if there is some way to find a particular driver that I need? Thanks :)

Without the output of that you haven't confirmed what sort of device it is reporting itself as. There is no guarantee that it does conform to the UVC spec, and if it doesn't then there is no point in trying to force the loading of uvcvideo.

Looks like it recognises it as a USB disk - so that you can copy recordings from it - and I think you can also make config settings by writing a text file to it (e.g. to set the time and turn off the overplayed time stamps).

When you use it in Windows do you get a live video feed?
