Case study

Prismatic: reconstructing SteelSeries Arena 7 RGB control

Prismatic reconstructs the SteelSeries Arena 7 speaker lighting exchange in a macOS menu bar app. It sends USB HID output report 0x06 with commands and RGB values for four zones, using a layout recovered from SteelSeries GG USBPcap traffic. The app controls left and right colors, brightness and power.
