Just got a brand new USB SATA dock, and when plugging it in to OS X consistently get 'USB Over Current Notice’s popping up (see attached picture)!](https://sslproxy.getsatisfaction.com/sslproxy/SWhAdDNLMG5zdGFuVGlWenmLbJDGd3CABhjZermgcystANA4T6nd0pzV0fSzBRRGOd17A4b8ZLwi6-HESbXI0glDJvEzlTlRKeS5xjchEs-p5n5vBfZLoSTYo52JObQp.png)](http://s3.amazonaws.com/satisfaction-production/s3_images/191160/box.png). Naturally the drive won’t mount. It’s not a defective cable (I’ve tried several cables that I have here), and it’s not specific to one machine (I’ve tried using two laptops and a desktop so far, and have tried all USB ports on all of the machines).
The problem occurs regardless of whether the unit is powered on or powered off when I plug it in (the messages appear instantly even if the device is off), and regardless of whether or not I have a drive docked in the unit. Do I have a defective unit, or is there another issue at play here?
