Thanks for contacting Plugable and for considering one of our hubs. Before recommending that you buy another hub, I want to make sure you’ve seen these support articles. It may be that you can get your D-Link hub working based on the following info.
Here is Apple’s official support statement: http://support.apple.com/kb/TS3169.
Here’s a repackaging of the Apple statement from a CNet writer, but in some cases the discussion forums on such articles can offer additional insights: http://reviews.cnet.com/8301-13727_7-….
Given the limitations that Apple defines it its support doc, I cannot say whether Plugable’s hub will behave any differently than the D-Link hub in your environment.
We have sold thousands of hubs but have not been hit with support cases about problems with attached devices not being recognized when a computer comes out of sleep mode.
We have had a few reports of unexpected drive disconnects when they were connected through the hub to a Mac, but the issues in those cases seemed to come either from a random fault with an individual hub (in such cases, we have replaced the defective units with new ones) or from an aggregate power consumption of the devices connected to the hub that was beyond the size of the hub’s power supply. With only two drives to connect, it does not seem like you would exceed the 2.5 amps available through the hub’s external power supply.
With all that as preamble, if you decide to purchase a Plugable hub, we would love to know whether it works as you hoped it would or has the same problem as your current D-Link unit. This information would give us data to offer a more definitive answer than I can provide here to a future customer with the same question. Or we may be able to find a solution for you. Amazon.com makes returns easy via http://amazon.com/returns if the product doesn’t suit you. And we’re always here to help with support should you have additional questions about a Plugable hub or any of our products (http://plugable.com/products)).
If I had to recommend a product, I would say that our 10-port hub offers the greatest flexibility (http://plugable.com/products/USB2-HUB…). Please note that its 2.5-amp power supply means that if you have five devices that each consume the USB 2.0-max of 500 milliamps of power, you only will be able to use five of the 10 ports.
Let us know if you have any additional questions, whether you were able to get your D-Link working, or your results with a Plugable hub.
