I have a set of 4 channel 900mhz headphones from a manufacturer in China. They have a USB port on them that when I connect them to my computer are detected as an unknown device. I need to be able to use serial commands to directly change channels on the device but I've been unable to find the right drivers or figure out how to gain any control. Ideally, I want to build a secondary board to enable remote control of the device, but first I have to figure out how to actually control it. Does anyone recognize these chips and can tell me how to talk to it?
