Is your board overclocked? Do you have the auxiliary back panel power plugged in? (floppy power connector near the back panel)

Look at user manual or at large poster with photo of SR-2 on it. There is everything written in many languages. This poster should be inside your SR-2 box.

Ok, here is my report after adding power to this connector:
Fist and foremost, a BIG thank you to antizax, who has made my day.

After adding this so called "optional" power source to my SR2 mobo, my PC is not recognizable. While it has been a super PC from day one, with incredible power, it has at the same time been "something" with everything that has to do with USB. USB 2, USB 3 - everything. I have a wireless keyboard and a wireless mouse, and the keyboard has been so flaky that it at times has been almost unusable. I got a USB extension cord, putting the radio sender 1 inch from the keyboard, it helped - a little.
After booting, and after the Windows welcome screen appeared, I often had to wait 1,2 and even 3 minutes before the PC responded to any keyboard or mouse activity. When at last responding, I had tons of strange typos, when letters I typed would come out in the wrong order. All of this is gone now. And the USB 3 external harddisk works as designed.

This "optional" power supply is a MUST - a big MUST.
The next thing I now will try, is my PCIe sound card which I had to ditch, maybe this one also will work now..

Again - do add power to this connection, all of you! And thank you again, all of you helping me with this

I can find two possible candidates for this.
1) 6 Pin required for Multi-GPU. This one I have connected to my PSU from day one
2) Optional 6 Pin PCI-E for CPU. There are two of these on the SR2 mobo, one located close to the PCIe slots, the other one far up on the right side of the mobo. They have a self adhesive label stuck on them, saying something like "Connect this for extreme overclocking". And these I have not connected since I do not overclock at all.
Firstly, do you think I should connect any of these under my point (2)? And secondly, I am a little curious about where I can fins some of the information you possess. All I can find is "Required for Multi-GPU",  nothing about that they are dedicated to any particular PCIE slots, like you write.
Any info appreciated

Ok, thanks. When it comes to the PCIe sound card, I have given it up and am instead using a Moto 828 mk3 equivalent which does not use a PCIe card, instead it connects using USB High Speed. This is ok, and I accept the solution. Although it is 3 times as expensive and not exactly what I wanted. And I think it is not as fast as my original ESI 1010e, it is all about ASIO latency.. Well, I spent weeks trying to solve the PCIe sound card problems, way too much time..
Maybe I will look into it again, just for technical curiosity, to see if powering up the USB Floppy "optional" connector has helped here too.  I say it would be interesting :)

Very Helpful information from our members here :)

Hi Ingvar,
 
Did you have any success in reviving your esi 1010e?
 
thanks,
 

How are you guys able to plug this Female (floppy drive) power connector into the female connector on the motherboard???
I have the same USB 3 issues and would love to get the power connected but I don't see how to use the black cable (your photo #1)..
Thanks for any additional info.

Just wondering if you sold your ESP1010e?  if not, do you want to?
 
Thanks
