USB keyboards - why cant use at bootup

[Mercenary Keyboard Warrior]

Hard to get a sensible description in title

I have a USB keyboard and have had a few others over the years.

Question is, it works in BIOS so I can do what ever I want the second it gets to the BIOS, so pc is powering it that early.

If however for example I need to select a dual boot OS or windows boot options after say a BSOD it refuses to work so I end up with the default or having to find and plug in an old PS2 keyboard ^^

Every USB keyboard I hav ehad has perfromed identically on different PCs so what is it that causes this issue and is there any way round it?

Its a lottery between the MOBO, BIOS & USB KB.

One USB KB will work as intended at bootup on one mobo but not on another mobo.
The same can happen with not working on the BIOS screen.

Had this problem with older mobos & was forced to use a USB to PS/2 converter supplied with keyboard.

I have the Gigabyte UD5(?) and it behaves like this. There's a setting in the BIOS about enabling USB keyboard that fixes it.

Check in the BIOS for USB options, maybe under the boot menu. Some Mobos have this option.

Never knew about that BIOS option, I can see that coming in handy one day .
