You can do it in two ways, here are both way

1. use PS2 Keyboard to get in to the BIOS. and here you can enable on board USB.

2. if you don't have PS2 Keyboard then pullout the C MOS battery from the Motherboard and wait for 5 min. after 5 min put into same place. now you can try all defaults are loaded and you can inter the BIOS.

Just reset the BIOS. Some motherboards has button, short two pins with jumper, or use a paperclip and short two points of soldered points. Check with your motherboard manual before do so. Removing CMOS battery sometimes works but not all the time.

since you've disabled USB ports pressing F2 will not work if you're using a USB keyboard. I recommend you to boot your system from a different source and format your system HDD or you can use a non-USB keyboard to enter BIOS setup and enable USB ports.

Use a PS2 type keyboard to get into BIOS or reset the BIOS by removing the CMOS battery and replace it after a few minutes.
