Just a question, what about the Power Supply? How many Watts has it?

Try resetting the BIOS to default, It might clear up the 'Device Descriptior Request Failed' problem.
Legacy mode is enabled: http://prntscr.com/d8zve2
Use microsoft message analyzer to capture the logs of your usb port when something is plugged. You can see there the details of the problem.
Doing it asap.
I will test that too, somehow I do feel that the psu is not strong enough. I disconnected the dvd rom to try to get a small bonus, if that matters, a long time ago.
If the psu will be at fault, then all I have to do is swear at the shop who sold me the pc, I was not limited by budget when I bought it a few years ago and I told them to be careful so the psu is great and supports the configuration and future addons, the cpu is great, etc. They managed to convince me to downgrade from what I wanted initially to buy, they said I won't need that and that.
psu choice is something difficult, you can not go only by the advertised watts, you need to investigate deep to find out the needs / output in the different lines +3.3,+ 5VSB, +12, -12 and so on. I mean , a cheap 650W will not deliver enough power in some Lines and pc will not work well, in the mains lines you get a lot of power but on side lines it is very poor, not enough for system.
edit: running a too small psu could lead that some hardware gets defective, it can be that your usb controller all already bad. i could not find what nvidia gtx 660 power needs in different Lines, may be you investigate that and compare with label on PSU.
That's why I asked the tech guys from that shop to do a proper configuration of the system, because I am not a tech guy. I took off the Nvidia videocard, and for now nothing new, the usb is still awol.
But, there is a big but. There are 3 different controllers, and the problems started around the same time. I am not sure if they could get ruined at the same time. 2 are on the back of the PC, 1 is in front of it.
So, how do I check if the PSU needs to be replaced? I can do that, but should I do it for the sake of it.
