Can't help with fixing the problem, but here's some info. When you are at the loader prompt, BIOS provides emulation of a standard / legacy keyboard for the USB keyboard. That's why loader can work even though it doesn't know much about USB. When a FreeBSD driver for the USB controller takes over then the BIOS emulation stops. Until a FreeBSD peripheral driver like ukbd attaches, it's not possible to use the keyboad, unfortunately. You can check your dmesg to see when that happens. Personally, I try to avoid "legacy free" solutions and always have a PS/2 keyboard (even if it's a really a USB one using PS/2 <-> USB adapter). Of course, it would be great to reduce the dead window for USB keyboards and I think that it is doable. -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
