Does the hub come with its own power supply ? Make sure everything is plugged in. Try to connect other HDD to threw the hub to the vero and see if it works.
It looks as if the HDD does not come with a power cord so that means that it pulls power from the usb if that is the case it could be that the hub does not provide enough power.
Indeed – if the drive is working directly in the Vero 4K, but not the hub, then it’s likely that the hub is going to be the issue.
You can get away with driving one hard drive with the included adapter without a hub; but it’s touch and go (we can’t verify all disks) and if you experience problems the first thing I would tell you to do would be to power the disk with an external power supply.
We understand that the 2 USB ports on Vero 4K is sometimes not sufficient, so we’re going to add a recommended hub to the OSMC Store in the very near future (next couple of weeks)
