Reply to VCI 100 SE Wont Turn On. Laptop Won't Recognize

Hey Guys,

I just bought a vci-100se and installed the latest 1.4 firmware version, it worked the first time i plugged it in and my laptop read the new device. the power also turned on simply from plugging it in. but now it does neither. I tried plugging in the usb, and the power doesn't turn on, nor does my laptop read the device. My laptops says "Cannot Recognize Device" [device has malfunctioned] or something like that.

Now it even says that when there is absolutely nothing plugged in to any of the usb ports.
In System Manager it reads "Unknown Device" when there is nothing plugged in to the USB ports.

Any ideas? If you can help me figure a solution to my problem, id greatly appreciate it. Thanks!

I'm Running:
Sony Vaio
Core 2 Duo 2.27 GHz
4GB RAM
64-bit Windows Vista

Please Help!
