Plugable USB-BT4LE Bluetooth 4.0 USB & Bluetooth keyboards in BIOS


Hello, I am wondering whether Plugable USB-BT4LE Bluetooth 4.0 USB allows to use bluetooth keyboards like Apple wireless keyboard in BIOS.
I heard that a HID Proxy is needed for this functionality - is that provided by the adapter?


Please answer, this is very important question. And it easy to check while having adapter in hand


Hi Andrey and Rudolf - Thanks for posting, sorry for the slow reply.

This USB Bluetooth adapter does not have any special in-built functionality for appearing as a USB HID device first (and emulating HID over Bluetooth), and then switching over to full Bluetooth functionality later (after OS loads).

Rather, it’s just a normal USB Bluetooth adapter. HID devices are only supported once the operating system’s Bluetooth HID drivers are loaded and talking to the adapter.

So a BIOS that only supports USB keyboards, won’t see any Bluetooth keyboards paired with this adapter.

Hope that background helps. Thanks again for asking!


Hi Bernie, thank you for such a full answer. Do you have any other adapters with such HID proxy capability? Sad it very hard to find…


Hi Andrey - Sorry, no.  This is the one adapter of this type that we offer.
