WebSection 4.2.6.10.1 - I have a question about LTSSM in Loopback state. When the LTSSM is in Loopeback.Entry(p.233L24), Loopback master will send TS1 with Compliance Receive bit (Symbol 5 bit 4)=0b and Loopback bit=1b and wait to receive identical TS1 with Loopback bit asserted less than 100 ms. In this time, both sides of link are probably in 5GT/s. http://xillybus.com/tutorials/usb-ltssm-lfps-power-management
