I wish to add a webcam model LarTek Full HD webcam 1080p to my bootable flash drive containing Ubuntu 16.04 so I can sign electrum transactions safely.

Ubuntu 16.04 can be written too but I never allow internet access and only run in trial mode.

Can I plug the webcam in and expect it to work with electrum without installing drivers etc?

I haven't tried it but Electrum supports camera though the 'Video Device' option in the settings: "Tools->Preferences->Video Device".
Then use "Tools->Load transaction->From QR code" to scan the QR code using your selected camera.

I saw your webcam model does not support Linux from their official website, yet I found a Linux review site about webcam, listing that model as a recommendation. Just to make sure you better try it directly on Ubuntu, just open up the default webcam app like Cheese on there, if it works, there's a high chance Electrum will also support it.

As vv181 said the best way to try is to just plug it in and test.

That camera looks like one of 1000 generic ones out there, so even if it does not work getting the drivers will not be difficult. It should be supported by the UVC drivers: https://help.ubuntu.com/community/UVC so if they were not installed when you setup the system you can still get them easily from a reputable source.

Most webcam these days is supported by Linux out of the box, although specific feature might not work. Most likely it'll work without additional configuration or driver. I would recommend you to use Ubuntu 20.04 LTS though if you're willing to recreate bootable flash drive since it has more up-to-date driver and Python.

I am using Ubuntu 20.04, though installed and not through Live USB. The webcam works perfectly without any necessity for additional drivers. I think you should go for it and shouldn't be worried.

Thanks for the replies.  :)

I will order the webcam, test on Ubuntu 16.04 or upgrade to Ubuntu 20.04 as suggested
