Dolphin doesn't remember pairings even with wii's dongle

[leonik]

Using Dolphin for some time, first with DolphinBar(it works in simple games, but bad with nunchuk or when gane needs second controller connected after game request(as in DK Returns)), in second i was tried BT passthrough, my builtin BT was not warking at all, so i found an old dongle, it was working fine instead of one thing - i had to pair controllers every time i start game. Finally, i get J27H002 wii dongle, and after some soldering it works now too, and still without pairing memory
I did some moves like deleting SYSCONFIG, i tried to remove Dolphin's profile, so it will start on clean new, but still with no result.

Any suggestions how can i resolve it?
