Advice for 90 Ohm traces of a USB 2.0 HUB
The pour is fine but it is too close to the traces and it ruins your impedance to be far lower. Same as if the PCB were too thin and the ground plane were too close. There is a 3W rule of thumb that says in your case that a diff pair with 10mil track width should have 30mil spacing to any track or plane. And the ESD diode should be in-line between connector and chip to protect the chip, not on a stub. Oh the stub is bad too.
