This is when I realized that the Bluetooth HID module is extremely convenient.

To make use of the Bluetooth Hub, I had to switch from HID-mode to HCI-mode and manually set the connections up.

I enabled the USB "/dev/hiddev raw HID device support", rebooted, and ran the hid2hci utility from the bluez-utils package.
(Another episode of: Where's that other keyboard...)

Well, after getting re-acquainted with my old keyboard I configured hcid.conf and started hcid, sdpd and hidd.

YAY! (2)

My devices were back online!
And this time, I had a hci0-interface in my arsenal...
