Vantec Nex. Star 3 Not Recognized via USB. I purchased a Vantec Nex. Star 3 SATA to e. SATA & USB enclosure (NST- 3. SU- BK) and it operates correctly when connected via e. SATA, however, it is not recognized when I plug it in via USB. Vantec indicates that it should be a simple plug- and- play device that will install automatically when connected via USB.

However, this is the error I receive: USB device not recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. It shows up in bold as Unknown Device.
This occurs with both Windows XP and Windows Vista. I am currently trying to get it to work via USB with Vista. The hard drive I am using with it is a Western Digital Caviar RE2 5. GB (WD5. 00. 0YS). There is no jumper on it because it clearly states on the drive that “Master/Slave jumper not required for SATA.” I have plugged it into each front USB and rear USB port, including those on the motherboard and it still produces the same problem. I have plugged it in internally, formatted and partitioned it properly. Again, it is recognized when connected via e.

SATA, but not USB. I have downloaded and installed the driver from the website, and installed USB Storage Toolbox. I have tried to manually update the driver to USB Mass Storage Device, and I have tried to search the computer (C: \Windows and all subfolders) for the best driver but still an error occurs. All hardware and connections are plugged in properly. I have even tried a different USB cable, but to no avail. Other USB Mass Storage devices work on my computer, such as my i. Pod, USB thumb drive, and external IDE hard drive.

I've searched many forums and either nobody has any issues with this enclosure or they have resolved them by trying one of or a combination of the things I have done. Does anyone know what the problem might be and what I can do to fix it?
