I wish I could say more about this, but after 6 hours of trying to make it work, I'm still on square one.

I have a cheapo usb dongle and a bluetooth mouse that I've verified works fine on my ancient (v10.5) hackintosh OS on the same laptop.
lsusb | fgrep -i blue
Bus 006 Device 006: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

I can get the bluetooth connection going, by using bluetoothctl power on/scan on/pair, etc. sequence. Connection and device info:
[NEW] Controller 00:15:83:0C:BF:EB BlueZ 5.15 [default]
[NEW] Device 00:60:D1:00:7B:9A Bluetooth Mouse

And I can see the new device appear on udev
udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[3050.213268] change   /devices/platform/regulatory.0 (platform)
UDEV  [3050.717106] change   /devices/platform/regulatory.0 (platform)
KERNEL[3059.596631] add      /devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/bluetooth/hci0/hci0:2 (bluetooth)
UDEV  [3059.598626] add      /devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/bluetooth/hci0/hci0:2 (bluetooth)
KERNEL[3061.071890] add      /devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/bluetooth/hci0/hci0:2/0005:056E:0061.0003 (hid)
UDEV  [3061.072648] add      /devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/bluetooth/hci0/hci0:2/0005:056E:0061.0003 (hid)
KERNEL[3063.220683] change   /devices/platform/regulatory.0 (platform)
UDEV  [3063.225657] change   /devices/platform/regulatory.0 (platform)

But there is no event/input device being created. So I assume this is the kernel mucking up, but I've enabled every single HID/bluetooth option I could find and that wasn't clearly for specific drivers.

Installed udev/gentoo-sources/bluez versions and use flags:
sys-fs/udev-208  USE="acl firmware-loader gudev introspection kmod openrc -doc (-selinux) -static-libs" ABI_X86="(64) (-32) (-x32)"
net-wireless/bluez-5.15:0/3  USE="cups obex readline -debug (-selinux) -systemd {-test}"
sys-kernel/gentoo-sources-3.12.13:3.12.13  USE="-build -deblob -experimental -symlink"

Edit: I also know the mouse works with linux, since about a year ago I had it working with another gentoo laptop (albeit using it's internal bluetooth).
Edit #2: CONFIG_HID_ELECOM=m was what I was missing. (facepalm)

Hope you guys can help, and thanks :)
