don't ask me. It is kinda hard to find a BlueCore4-External dongle these
days. And I actually need some where you can flash new firmware into it.
If anyone find a reliable source of these, I would buy at least a
handful. The best ones _were_ the Level1 things, because they used a
high quality flash chip. However the new ones have ROM chips as well.

The CSR unified firmware has a boot parameter where you can tell it to
boot up in HID mode or HCI mode (and some other modes). In general every
unified firmware is HID proxy capable. You might simply have to switch
it on.
