O.k. I tracked it down a bit more, but would like some input. Command executed: "insmod uhci; echo 1; insmod usb_keyboard; echo 2; terminal_input usb_keyboard; echo 3" Basically uhci and usb_keyboard load consistently now, for whatever reason. (I suspect it was sth about some weird device just taking forever to respond, although I wasn't able to reproduce this) I get returned to the prompt, but no input is accepted. I tried to put some debug statements into console.c and some others I think have to do with terminal_input but those don't show up, however the last "echo 3" does appear. So I would like some pointers on where it would best to insert some more debug statements, or maybe if efi/console.c needs to be adapted to work with usb_keyboard, as I understand that at first it only was included in the compile for i386 anyway ...
