10.8.5 Bluetooth problems

Hello,

i'm having trouble with BT since upgrading to 10.8.5

I'm using a BT serial adapter - whch was working fine before.

Now, I cant get a terminal when conneting nor can i update the serial ports provided by that device.

Removing the device and pairing again works - but using it fails.

I read about some BT problems after upgrading, but nothing helped so far...

Anybody has experienced a similar issue?
