The post on Plugable's 7-port charging hub power setup is from me

Possibly using Y-cables is contributing to the drop out?

I run 2x 2Pacs and 1 Compac on the Plugable 7-port 60w charging hub.
For form-factor and cooling I have a 2Pac on port-2, the other 2Pac on port-4, and the Compac on port-6. Nice and compact for cooling and each stick is on its own buck.

Tried running them without the y-cables, just plugged straight into the hub?

I did earlier, and again last night - they were dropping like flies :/ After only a few minutes one of the stick would drop and Found 0 chip(s) fun would begin. Also tried swapping cables - nothing changed. One would work, the other would drop out.

Then I decided to go back to basics. I connected only one stick, via Y-cable to the Pluggable hub, and just for fun of it I upped the frequency to 275, two original Compacs were on other hub, second 2Pac was taking a break. Started cgminer... 19 hours later, 2Pac still going strong, averages at 30Gh/s, 0 HWs. I guess 30Gh/s @ 275Mhz is expected - Compacs @275Mhz would give somewhere about 15Gh/s.

And to make things more interesting I've connected "special" stick to Pluggable, an hour ago, using Y-cable but connecting just one end to the hub and then I ran another instance of cgminer @ 150 Mhz.

Now I have one cgminer running 2Pac@275, 2 Compacs @250 and second cgminer running one 2Pac@150 - so far so good...
