iMac 5k With Yosemite wont boot with USB 3.0 Hub

[ansabakhan]

I got the new iMac with Yosemite installed, the problem is that my iMac wont boot with this usb 3.0 (hub below)attached and wont find it if attached later, I am guessing OS X Yosemite is not liking the hub? is there any solution to this ? any one else encountered a smiler issue.?

HUB not working with Yosemite

Maybe that huge hub is drawing to much power?

Plus after all the Reset Pram and the SMC and then try a different port on your iMac at either end of the back ports.

hi, I tried doing the PRAM and SMC... nothing works...

what I start computer with USB attached, i hear the sound os startup and screen stays dark.. nothing will happen after that...

if I remove the hub, all seems to work fine...

That does seems strange then. First then make a Test account and try to boot into that with the hub connected. If it still fails to start normally with the hub then go back into you own main account and give Apple FeedBack. Make sure be as detailed as possible. Plus call Apple Support ASAP if your iMac is new within 90 days.

One last thing, are you using the included power adapter with the hub? I ask because the Amazon picture shows a power cord to the hub.
