Hi Sirs,

Sorry to bother you.

Our USB function block as below. (Use mux control, one path connect to UFP mode, another path connect to HUB)

Could you help review our schematic?

Any suggestion are welcome. Thanks!!

you seems have two muxes on same USB3 path, it may failed USB3 compliance test, suggest to use USB redriver at SUC-C connector

Hi Sirs,

Thanks for your reply.

TUSB322I's I2C & INT is connected to the CPU (arm based)
Controlled by the CPU
Does this need a driver?
