Hi,

The TUSB551EVM uses a Type-A plug instead of a Type-B receptacle and the appropriate pins are labeled differently. Type-B receptacles are labeled from the device perspective where SSRX is the USB Host TX coming from the cable assembly.

Hi,

The above image seems correct assuming RX_UP is (RXN,RXP) not (TXN, TXP).
