Universal Serial Bus (USB) is the world’s most popular and widely used
computer interface. Layout of USB designs is not complicated, but you must
keep several factors in mind to preserve signal quality.
This video explains the most common layout topics for USB
signals: impedance, trace length and matching, and printed circuit board
(PCB) stack-up. The examples we provide focus on USB 2.0 high speed, but
the lessons also apply to USB 3 Gen 1 and Gen 2.

Could you please share a video with a demonstration for USB2.0 routing?

Has to be SHIELD on USB connector of connected PCB to PC grounded ? Thank you

It is mentioned 8ps delay for 5 mils mismatch is acceptable for USB 3.0, but it is actually 1 ps delay for 5 mils.

"Taking care not to route at right angles over power plane splits" Can someone give an example for this case?

I suppose you have already found the answer as there're plenty of examples if you put this string in a search engine. For others reading this - this is a very important point and not following it will create EMI and signal integrity issues. Try to avoid splitting ground/power planes when possible. For the right angle trace turns - previously there used to be etching problems but now the main concern is --fast electrons will derail-- sharp edges act as emitting antennas, so again EMI and signal integrity issues especially for fast signals.
