Can't use USB keyboard during boot menu

I've already had this problem in the past and seems it's back now.

I use a Sun Type 7 USB keyboard. When my box is booting, and
FreeBSD menu shows up, I cannot press any key to go for a
single boot for example.

ugen1.1: <UHCI root HUB VIA> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen0.1: <UHCI root HUB VIA> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen2.1: <UHCI root HUB VIA> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen3.1: <UHCI root HUB VIA> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen4.1: <EHCI root HUB VIA> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
ugen3.2: <product 0x100e vendor 0x0430> at usbus3, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=SAVE
ugen3.3: <USB Mouse vendor 0x0566> at usbus3, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON
ugen3.4: <Sun USB Keyboard vendor 0x0430> at usbus3, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON

Please let me know if you need more data.

Thanks
