We got ourselves an AMScope stereo microscope with their MA500 camera – the camera more or less came for free with it. The problem with the MA500 camera is that there is no Linux driver for it and AMScope has no intention to provide one.
So I took the camera apart to see what’s inside. I found a Cypress USB chip CY7C68013A-56PVXC for which you can find a datasheet here: https://www.cypress.com/file/138911/download
This is a USB microcontroller, basically a programmable USB to parallel port bridge used in quite some devices. It can and probably will take a firmware download after power up. I will need to take the Windows driver apart to find it.
