I recently purchased a two Belkin hubs:


1) Thunderbolt Express Dock

2) Four-port USB 3.0 hub


With both devices I find problems mounting external USB disk drives. While the problem could lie with Belkin, with whom I am having a fruitless discussion, I want to rule out any potential conflicts in OS X drivers.


The Thunderbolt Express Dock works perfectly with Thunderbolt peripherals and the Ethernet connection is constant. However, when I mount drives, whether USB 2.0 or USB 3.0, whether powered or bus-powered, the drives mount for a short time and then unmount with the usual warning message about prior ejection.


With the USB 3.0 hub, despite the power connection to the hub being verified, I can get no disks to mount. The lights are showing against the respective sockets on the hub but the computer is not recognising the drives.


I realise there is no way anyone can comment on the Belkin products, although both are sold in Apple Stores, but I find it curious that this problem is occurring. Could there be some common problem relating to the drivers or to the settings on my compuers?


For the record, I have tried connection to two different Macs, both running 10.8.4. One is a 2013 15in MBP Retina, the other a 2012, 11in MacBook Air.

    Have a read of the discussion started by AWMarine

    who appears to have tested a number of usb 3 hubs. I think you may find that it is nothing to do with Belkin.


    I have just found the same problem with a new USB 3 hub (anker) and am having to return it. You may need to wait until Apple get their act together to make usb 3 work properly.

    Any updates if the Belkin Thunderbolt Express Dock on which you plug a USB 3 external hard drive, on whether it is stable for Time Machine, that is if the disk unmounts?
