Usb 3.0 port with usb 2.0 cable?

I have MacBook Pro mid 2014 which I understand have an usb 3.0 port.

I wonder if I can use it with usb 2.0 cable to connect to an arduino..?
Does Arduino support usb 3.0?
what are the differences between 2.0 and 3.0?

Can I use usb cable extender of 10M + 1.8M of the usb cable itself or is too long for usb?

Thanks

Yes

No, but USB 3 supports the Arduino.

And the original one.
Well mainly speed, and the amount of current it will supply. The speed thing is a negotiation so it sorts itself out to the maximum speed both ends can cope with. There are also more “modes” in the higher version numbers.

It depends what you are putting down it in terms of data rate.

Thanks for your replies!

what do you mean by putting down?
I mainly print some strings to the Serial

Sending down the cable.
For example an Arduino would not cope with high speed digital streaming anyway, if you wanted to do that you would have to use a higher USB standard than USB 1.

ok, thanks!

@R_Gol Avoid using a USB hub or USB 3.0 port with Arduino.

I currently have 2 Nanos and 2 ESP32s plugged into a USB2 powered hub all working fine but I would not trust an unpowered one
