Only thing that didn't work was the key repeat, but I guess > that belongs into vkbd(4) (According to the HID profile spec, the > host has to handle this). hmmm... i think, microsoft bluetooth keyboard did send repeated reports when key is pressed and held. i will double check this with apple keyboard. > Do you have a todo list for kbdmux, vkbd and bthidd? yes. there are two major issues with kbdmux(4). 1) kbdmux(4) causes hard lockup when ps/2 keyboard added to kbddux(4) and ps/2 mouse is used under x11. if i replace ps/2 mouse with usb - no problem. my current theory is that kbdmux(4) somehow changes access pattern to ps/2 hardware and something gets written into wrong place. 2) alt, ctrl, shift state synchronization. under certain condition kbdmux(4) alt, ctrl, shift state may become different from what raw keyboard think it is. vkbd(4) is fine for now, i think. i do not like code duplication in all keyboard drivers, but that is another issue. bthidd(8) is missing man page. it needs to track double click mouse events (they work under x11, but not in console). need to fix handling for special keys (pause/break). perhaps need to add/fix support for multiple bluetooth keyboards. also, i'm not very happy with the "keyboard switch script" idea in bthidd(8). if/when kbdmux(4) will become default this should go away and appropriate changes to /etc/devd.conf should be put in place. thanks, max
