I have a system where I have implemented USB 2 that uses long traces and cables. To accommodate for the long traces and cables and still pass the USB 2 eye mask compliance test I used two USB 2 redrivers. When both USB 2 redrivers are enabled my system can pass the USB 2 High Speed (HS) eye mask test but when I plug in a USB 2 HS device the USB 2 data drops out, is there an explanation for this?
