Topic: Wireless Buzz Buzzers PS2

Hi, maybe someone can help me… I tried lot of things and no solutions!!
I have 4 wireless buzz buzzers for my playstation 2 and some games used for these controllers (original and Iso). Anyway, I can´t seem to get them to sync and be recognized on my PS2 (fat one). I´ve done some searching around on various forums and the Google and what little info I´ve found hasn´t helped. Do you have any suggestion about getting these things synchronized?
Basically, I´ve gotten them so they are all solid blue light, then hit the sync button on the dongle and they all flash and then no lights are on (neither on the buzzers or dongle). I thought this meant it was set, but the game is not recognizing the controllers. Any help would be appreciated. Thanks

@josefalhanga Stupid question, but are you trying them with a Buzz game or a game that supports Buzz controllers?
