I have tried different USB cords/sticks configurations etc....it must be some kind of USB restriction?
Can you please help me with this?

I'm sorry I can't help with this; I can answer your second question.

As a side question what's the minimum USB voltage they need to run?
I know there is a voltage pod, so theoretically I can even run them at 4.3V (at the hub side) if my voltage at the chip would be ~1,45V correct?

The buck converter circuit should give you a stable output, as long as the input is in a relatively normal range. I've seen 5V USB devices running on anywhere between 4.7 to 5.1V normally, but it's possible that 4.3 could suffice. Do note that the potentiometer doesn't affect your input voltage (5V side) but just the core voltage; so it's possible that other components such as the buck controller or FTDI chip will stop working even though the core is happy.

The only problem I see is my hub shows 5.2V when NOT hashing and sticks starting up and if I adjust the screw, until I'm at 1.45V DURIUNG mining for sticks stability, it could possibly go way above the 1,45V at the INITIAL stage of mining, when sticks are just starting up and not hashing yet, would that be a problem?

I don't think 5.2V is too much out of the ordinary, but I'd be careful of having voltages on the core of 'way above 1.45V' (how much is 'way above'?).

Another side question - what file is a config file for current version of cgminer? I have used the save option during mining and now it looks like no mater what options I run the miner with it will run with the saved ones, I looked in the cgminer folder and there are tons of various config files. I assume if I delete the config file it will revert to default settings?

It takes the config file if you specify it. I.e.: run it with the -c or --config parameter and pass the config file's path.
The contents should look something like this:

Quote from: https://github.com/kanoi/cgminer/blob/master/example.conf

Code:

{
"pools" : [
{
"url" : "stratum+tcp://stratum.kano.is:3333",
"user" : "username.worker1",
"pass" : "x"
}
],

"failover-only" : true,
"api-listen" : true,
"api-port" : "4028",
"api-allow" : "W:192.168.1.0/24,W:127.0.0.1"
}

After you input the information you otherwise pass by command line args into that file, you can run it with simply ./cgminer -c example.conf.
