Plugable UGA 2KA won't power on after second connect in MacBook Pro

I have a MacBook pro with Lion 10.7.2. I installed the displaylink driver last week and the Plugable UGA 2ka was working fine until I brought it home from work for the weekend.

When I reconnected the adapter to the MB Pro this week, it stopped working. The LED light won’t turn on and the external display says “DVI no signal”

Would you know how to fix this?

Hi Huy,

This would give us a better insight as to what is going on. Once we analyze it, we can figure out the next steps.

Thanks for your patience!
