OS X Mavericks :: Pairing Bluetooth Presenter Doesn't Work Anymore

I have a bluetooth remote presenter. It has the usual keys (next, previous, volume, play/pause, start default music player) and it also has a small touchpad / trackpad with left and right buttons, scrolling buttons. 

The remote is great and it served me well under Windows and OSX 10.6.8 Snow Leopard. Now since I bought a new machine with Maverics, I can't pair it. The bluetooth utility looks different on Mavericks. Certain things missing, such as making Bluetooth discoverable or not in the way of simplification of things or oversimplification of things, where there seems to be no access to Bluetooth device details and no way to add device without pairing code. 

The remote is recognized as mouse with keyboard, which makes things worse, there is not only no code on the device, even if there is one (or if it would except 0000, 0000000, or similar), I have no way to enter it. 

Unfortunately Maverics made things simple but useless for some bluetooth devices. It's unnecessary. 

Seems like I will be stuck with Snow Leopard on one of my machines forever. 

When I look in console on SL, here is what I see: 

2014-06-28 8:23:11.268 AM System Preferences[7658]: [establishKernelConnection] Received an error from IOServiceOpen() - 0x10000003.  NULLing out io_service_t. 

There is an entry like this every time I try to pair. 

The Bluetooth manager window says -- "Pairing failed" 

When I go to Options, it shows the field to enter code. No matter what I enter there or if I leave empty, I won't be able to pair. 

Otherwise BT works fine on Maverics, I have Apple keyboard, Logitech kayboard, Apple and Logitech trackpad and audio device connected, no issue. 

The Remote presenter works also fine and I tried to re-pair it with other non-Mavericks machines and works fine too.
