This is probably a silly question, but I cannot find an explanation. How do I properly disconnect Trezor from a Windows or other device/machine? Do I just pull USB cable out at any time I wish? Do I need to check for some process(es) to be completed? Thank you!
Just rip it out.
(using the normal amount of force that you usually use for disconnecting USB devices. wouldn’t want you pulling at the cord with all your might)
The “safely disconnect” is not a general USB thing, it only applies to USB storage such as flash drives or external disks. Trezor is neither.
