Support hardware interrupt

[mickaelv]

Hi,

Thanks for your script !

Is it possible to add hardware interruption to use snapshot button on UVC device ?

I know that the status packet must be like :
bStatusType : 2
bOriginator : 0x00 Button Press
bValue : 0x00 released, 0x01 pressed

But actually I don't know how to easly get this status packet

Regards,

Mickaël

This is possible, but I would have to do some digging in the uvc docs to figure out exactly how. What device are you using that supports this? I have never seen a snapshot button on a webcam

I don't have a device to test hardware interrupt, but I could make it work programmatically
