I have a webcam connected to a FreeBSD server that I want to collect and email an image on a schedule via a cron job. The room it is in may not always be lit. I am hoping to find some solution where a light can illuminate the subject just at the time of the photo. As a first stab, I bought a cheap USB lamp from Amazon and then tried using usbconfig to power off its port, but alas, this had no effect on the lamp. (Also, the port seemed to disappear permanently and could no longer be addressed by usbconfig -- probably something I just don't understand about the process.)
This server is running FreeBSD 12.1. Does anyone know of a reliable and affordable way to do what I need?
