The thing keeps disconnecting and reconnecting every 5 seconds

[rg12]

Hello
I just got my displaylink thingie and it worked for the first time but after a
while when i got back to my computer i noticed that all my screens are flickering
so i opened the display details in win7 to show me how many screens are
connected and the thing keeps disconnecting and reconnecting about every
5 seconds non stop.

I tried installing the latest driver and nothing.

Tried disconnecting the unit from the usb socket and reconnecting and still nothing...

Any ideas?

Thanks,
Roi.
