Unknown components in a schematics of a Micro-USB connection
Why are the resistors with 0R?

That's a very common notation: R is for &quot;resistor&quot;, and is placed where the decimal point in the component value in ohm would be (because Ω was hard to produce back in the day). This is a 0 Ω resistor – in case you analyze your device and figure out later that a USB-compliant termination resistor is actually necessary.
