I dont want to send anything back , unless you think its broken

What does Zombie mean? does it mean its broken and cant be fixed? Is there anything I can do to ensure that it stays mining and not saying ZOMBIE ?

I have an antminer u3
7 port Powered USB HUB, with AC adapter
ZADIG 2.1.1
CGMINER 4.8.0

I actually also had this problem at the beginning. After removing the powered hub between the antminer and my Raspbian, it stopped displaying Zombie in the cgminer

That's a good idea. Going zombie on these is typically due to some form of interruption, the most common being power / USB power related.

Mine goes ZOMBIE about once per day. Sometimes twice in one day, sometimes it runs for 2 days straight. Is it a defective unit or not? I use CGminer 4.9.0 with no options. Plugged directly into a USB port on my desktop PC.

is not the USB port version 3.0 [blue color inside]?

There are lots of small, annoying things which can make it go zombie as there only has to be a very brief interruption for it to kick out. It might be you're using USB 3.0, or using it via a powered USB hub, or not using it via a powered USB hub, or the power supply overheats / flickers. Or, the product itself could be flickering to the point that its 'faulty'. Either way, you're free to return the product for replacement to our US base.

Thanks. As a point of reference, the Ant U2's in the same type of USB ports NEVER go Zombie. The only difference is that they don't have a power supply.
I will return it, but I believe I need an RMA #, right? I'll send it to the CO location.
