Hello Sir or Madam
Thank you for your inquiry. Unfortunately, the IB-3810u3 is a product from IcyBox, not IcyDock. We cannot provide assistance to that product as it is not our product. Please verify the model number you are inquiring about.
The closest product we have is the MB561U3S-4S R1 (http://www.icydock.com/goods.php?id=218) that connects via USB 3.0 and supports up to four 3.5"/2.5" hard drives at one time.
If you have any questions on our products, feel free to contact us.
