Bluetooth Adapter/Dongle With HID Proxy Switching To Access Bios.

Don't Know if this is the right place to post but I have a Logitech Bluetooth Keyboard that I can't enter the bios with as Bluetooth isn't 'on' till after boot.
I have read though that some Bluetooth dongles have 'HID Proxy Switching' which recognizes the Bluetooth device as an HID USB device at boot, then you can enter bios, it then switches back to Bluetooth when OS loads.
Anyone know more about this and can recommend an adapter/dongle ?

For anyone that cares to know, The Rocketfish Bluetooth Dongle at Best Buy does indeed have 'HID Proxy Mode' allowing the computer to 'See' a bluetooth keyboard as a USB device at start up so you can enter the bios.
