Hi! Can you explain why brltty 5.0 take my hims braillesense u2 and brltty 5.2 not? If I can help what I have to do to test the response of the braille display via usb to see what append when I pressed anay key or so on. I remark that the way to code in brltty 6.2 change a litle bit does this the way to code that my hims braille sense u2 doesn't work?
