So, I have this problem that I cannot figure out. My netflix watching machine is a VM in my basement, I run HDMI and USB up to the living room through the wall. The HDMI has been rock solid. For two or more years, so was the USB. All of sudden, the steam controller started doing this thing where it appears to work but loses connection (as in drops input) for a few seconds every 10-20 seconds or so. I replaced the active extension cable at one point and the problem seemed to go away for a couple months at least.. Then I moved some stuff around and it came back I stripped most of the stuff down, tested it all in the basement and separate and it worked. I put it back together and it worked again for a month.
Well, I did an upgrade. And now it doesn't work.

The last thing I did was I plugged the steam controller in directly and tested right next to it. Seemed to work fine. Then I plugged in the extension and the steam controller stopped working well again, it wasn't even plugged into the mess of wires, just plugged in NEXT to them.

All of my USB ports are 3.0 I'm testing. But all of my extension cables and hubs are 2.0. I saw recently that interference can be caused by 3.0 in the 2.4ghz band...but I'm not actually using 3.0 so I'm not so sure.

This is driving me nuts because it DID work fine for years. I've replaced everything by the way....EVERYTHING. I server is all new hardware, I replaced the bugs and extension cables and used different steam controllers. It seems like some kind of radio interference but I tried turning off the wifi access point (which was always there) and it didn't help.

TLDR; How can you get around USB port radio interference? Is that what I'm dealing with?

So I didn't really solve this, but its working at the moment.

I relocated the server to its final location and removed hubs from the chain. I found that having the hub chain plugged it caused the problem even if I was plugging the steam controller into entirely different USB controllers. These are all USB 2.0 hubs and they are powered with AC bricks. I've never heard of USB 2.0 hubs causing these kinds of issues and I'm still not entirely sure that was the cause.

I'm not even sure its the hubs, I've been wrong so many times with this problem I don't know what is going on. This same stupid hub chain was working fine for awhile.

I'm sure when I add another active extension cable to the mix everything will crap up.
