I have synced my 9530 & 9550 with Device Manager for over 2 yrs with littie issue. As of 2 days ago DM locks up as soon as it connects to the device (USB & Bluetooth). 10+ hours of tech support with RIM and they finally tell me its a known software glitch and they have no idea when of if they'll get it solved. Verizon doesn't even know about the issue. Anyone else experienced this?
