Is it supposed to be FTDI manufacturer?
No, its supposed to be WinUSB. Is CGMiner giving you an error message? If so why no post the text so we know what it is?

sorry had it as a link earlier in thread.
Are you plugging this directly into your PC's USB port? If so USB 1.1, 2.0 or 3.0? Or are you going through a Hub?
It seems like a hardware issue like Kano said. Especially since it happens immediately.
Oh, as for links I don't click on them. You can also copy and paste the text too.
