I am assuing you are seeing a hardware problem. I am using more or less your exact setup, on a Raspberry Pi 3, with the original small-size PS/2 keyboard shipped with the Braille Star 40, and I can not really report keyboard issues. I have occasional initialisation issues when turning the display on, but I kind of attribute this to the somewhat strange USB chip in the Raspberry Pi. I have other issues like the rpi not booting while my external USB storage is connected, so I am sort of used to seeing weird things related to USB. However, no apparent keyboard issues here. The scancode passthrough has actually always worked quite reliably for me, since it was implemented around 2003 or so... -- CYa, ⡍⠁⠗⠊⠕ _______________________________________________ This message was sent via the BRLTTY mailing list.
