I am trying to install FreeBSD.
During the install (actually at the beginning of the process) the system

When it gets to the select country screen...it is frozen.
During the boot process, as it is reading all the hardware, it finds the USB
controller OK then later it states there was an IO error and that the USB
controller is halted. I have a USB Keyboard and mouse...so I would say the
problem is here.
Is there any workaround I can use to get things going?

Set "USB Legacy Support" to disabled in the BIOS.  If that isn't
available, it might work to boot with the keyboard detached.  Connect it
after the BIOS boot, at the FreeBSD bootloader prompt or maybe at the
country select screen.

I don't see how this would solve or even affect his problem.

As I understand it, "USB Legacy Support" is intended for operating
systems which do not have a USB stack available to them, thus making USB
keyboards/mice appear as PS/2 keyboards/mice within MS-DOS and so on.  I
believe the way it works is that the BIOS acts as a software translation
layer between the USB device and PS/2 interaction.  This translation is
lost the instant interrupts are re-mapped or the southbridge/USB
controller is initialised.

The OP is making it past boot2/loader, the kernel and all its drivers
are fully loaded (including the USB stack).

An MSI motherboard did the same thing, only with a USB mouse. The BIOS defaulted to legacy emulation. The mouse would be briefly enabled during boot, then disabled as FreeBSD started. I found a message explaining it, disabled BIOS emulation, had no further problems, and... didn't investigate further. Now I can't find the exact post, but did find a thread that is similar:
