USB4 / USB5 support

Does the laptop support USB 4? And in the future when USB 5 is released would it be possible to upgrade the motherboard that supports USB 5?

The product description states that the USB-C expansion card (and thus the motherboard) supports USB4.

Currently no USB5 specification exists, let alone any hardware that supports it, so it is not possible to make any specific claims. Do note that Framework staff confirmed that they intend to offer motherboard upgrades in the future.
