Whilst I was still using my MacBook Pro I had also been using a USB Hub, although due to power restraints I had to upgrade to a Powered Hub. After a little research the D-Link 7 USB 2.0 Powered Hub seemed to be the way forward. I ordered it up and upon its arrival I plugged in it, stuck in in the MBP and now had an extra six USB 2.0 Hubs to play with.
On this machine it worked flawlessly, never missing a beat, my machine didn’t have USB3.0 so that wasn’t an issue and this hub happily powered four HDDs (2 of which were powered, 2 were portable). It also worked whilst syncing my iphone / ipad and camera. No complaints whatsoever on this machine.
This specific Hub also has two ports which are dedicated to charging. They are ports six and seven, and if your machine is powered down but the hub is still on (via the wall socket) you can use ports six or seven to charge your phone / tablet etc. It does not charge whilst the machine is in use.
For reference the machine this Hub was being used with was a Early 2011 MackBook Pro i7 2.2GHz (1Gb Graphics), 8Gb RAM, USB 2.0 with a Apple Cinema Display attached via Thunderbolt.
Then came the problems. I upgraded my computer to an iMac. It was at this point that this hub stopped working.
Again for reference the machine it was being used with was a late 2013 27″ iMac i7 3.5Ghz, (4Gb NVIDIA Graphics), 8Gb RAM, USB 3.0.
In this set up I used 3 of the 4 USB 3.0 ports on the rear of the machine to deal with three USB 3.0 hard drives (2 portable and one powered). The forth port was used to power the D-Link Hub. At this point only 2 hard drives were being used in it (both themselves powered desktop drives). This is when things started to fail. Both drives would mount momentarily, then disconnect with errors, mount -> disconnect and repeat! If you removed one drive the other mount successfully (either drive). Either drive would successfully mount via the USB ports to the rear of the machine.
For some reason when both drives were plugged into this port things failed. My only option was to bin the hub and try again with a new one. A quick Google search for USB hub problems with an iMac do tend to suggest that this is an issue with many hubs and the power they require as opposed to what they actually supply.
As expected customer service from Amazon was excellent and a new hub was ordered.
