The Trezor firmware upgrade procedure is not handicap friendly. You may be thinking so what, but consider you may find yourself likewise one day, you know, the day you start hating the world?
Could you be please more specific? Do you mean that it is hard to press both buttons at once, or something else?
Need two fingers of one hand to press the two buttons. Then you need another hand to plug in the USB cable.
That's two fairly nimble hands required to update the firmware. People with handicaps (heart stroke victims, missing limb due to diabetes or war, etc.) will have a hard time to do the firmware upgrade.
I'm fairly able but it took me two tries because I didn't press down hard enough. Then the realization came to me about handicap people or even people with arthritis are gonna have difficulties. People with just one usable hand? Nearly Impossible.
