Description
So it seems that some usb keyboards are not working on Haiku because they send keystroke reports using a bitmap instead of the more common way of using arrays. Perhaps, I should have opened a bug ticket with this... Instead, I have ended trying to fix myself, and I almost done, but I am blocked by a bug.
The report descriptor, from what I understand, defines a 8 bit constant padding and a 112 bit with current keystroke status. Whenever I press key A, with usage 0x04, I get an I, with usage 0x0C, and so on with B,C,D,... So it seems that padding is not being honored.
disclaimer: I am not a usb hid guru and I may have done some wrong assumptions
