Re: VLI firmware v2.0 - powersaving features enabled

Troubleshooting noname USB webcams isn't going to be possible - unless there's a generic issue with the transport protocol in question. Unfortunately, I do not have other information, but I still do not think that this is a problem with the cameras. These models were used by me on various devices w...

Re: VLI firmware v2.0 - powersaving features enabled

Wierd. I would expect performance degradation (in the off-chance we've not explored some set of wakeup latency/servicing interval required by the cams) and not a complete failure. I don't think this is a complete failure. With reduced bandwidth requirements, I can sometimes capture individual frame...
