Hi Brian,

Thanks for ur reply, I have another question about USB compliance test, I have two USB 3.1 HUB(TUSB8042A), and the secondary hub upstream port connect to the first HUB downstream port 3, all the USB HUB#1 downstream port connect to IC (like TUSB9261 . TUSB8042A . etc), and all the secondary HUB connect to the USB Type-A connector, so I have to set both TUSB8042A HUB to compliance mode when I do the compliance mode test right?(USB 3.1 gen 1 & USB 2.0/1.1/1.0 test)
