Why do USB drives plugged into USB hubs make my Mac Book Pro (Retina late 2013) wake from sleep?

Question

I have 2 x USB hubs, a Logitech USB 2.0 hub and a Broway USB 3.0 hub. Tested both and both seem to be the cause of my late 2013 Mac Book Pro waking from sleep. I ran syslog to find out why (syslog |grep -i "Wake reason") and the reason I got back was "kernel[0] <Notice>: Wake reason: XHC1" - this means nothing to me, but it didn't take too much mucking about to hunt the problem down and figure out it was the USB hub with any USB drive attached. If the drive is attached directly to the computer. No problem, computer sleeps fine.
This was a problem I encountered (and never solved) with OSX 10.6.8, a 2008 Macbook Pro the same Logitech USB 2.0 hub, but with different drives. I put the problem down to a bug that never got solved in an old system. But I am simply AMAZED after my update to a new MBP and new system that it is still about almost 6 years, a dozen MBP's and 4 systems later.
The other problem is that not only does the USB drive/ USB hub combo wake the computer it also loses the drive upon sleep and mounts it again upon wake. Then repeats this process every couple of minutes. And it obviously doesn't eject the drives properly because each time I return to the computer after I put it to sleep or let it go to sleep I get a giant list of "Disk Not Ejected Properly" notifications about it. Which I'm guessing could eventually cause some file damage.
I've tried combinations of different drives, different hubs (a Belkin and a no-name Chinese brand 2.0 hub) and the problem persists. Is there a solve to this problem? I'm surprised to see so little posts on forums about this. Am I just unlucky and got another combination of faulty/problematic hardware, or is this a real problem that exists for everyone? If not I would love to know if people have found winning combos of USB hubs and drives. But if it is, then it HAS to be solved.
If you have a Macbook Pro, then you are limited to 2 USB outlets, this is obviously a bare minimum and I would say that 95% of people using their laptop computer in the office or at home have a hub, and very likely a USB drive attached to it. I know actual Apple reps don't really pay much attention to the community support posts, but I've got 6 months worth of Applecare left and would like suggestions about how to get Apple's attention about this problem.
BTW Jettison (a 3rd party app that ejects drives properly before sleep) is not a solve. It is a 3rd party app that tries to fill a hole in a broken system. I don't want to eject my drive upon sleep, I want it to got the **** to sleep.

Answer 1

Is there a pattern to the time of day or other detail that may be
traced back to a OS X system cause of this odd phenomenon?
Are there any copies of system files on any of the attached USB
external drives? Any libraries, such as iTunes, iPhoto, etc?
Once the drives are indexed by Spotlight, are their permissions
ignored by the OS X? Content, if neutral, should not affect the
wake or sleep cycle; especially if they're ignored by the OS X.
Could there be a bad cable or other component? If so that would
be a difficult process of elimination to detect it. Usually replacing
most suspect components in the USB stream (external to Macs)
is a rote way to mechanically test that idea; & not 100% sure.
Does the equipment all have a good ground to the utility or house
electrical field? An intermittent ground may affect more than sleep.
Hard to say at this point. Maybe a late-night talk radio guru on
remote viewing could peer into your situation and sleuth it out?
Sorry to have run out of ideas, but the process must be electrical
& mechanical to some extent. - Or perhaps odd software inspired.
Do you have any phone-home spyware items inside, just jumping
at the chance to spill your information? Little Snitch may help.
PS: Perhaps the computer needs to go into Apple & have a genius
or product specialist at AASP test the unit thoroughly... BlueTooth?
