The Yamaha KX61 is a very nice USB-powered MIDI controller. I have owned a pair of them for about 3 years.
While trying to reorganize the dozens of USB cables in my home office, I found out the following problem : if the KX61 is hooked up directly to my PC's GA-990FXA-UD3 motherboard via USB, the PC is unable to stay asleep. More precisely, the PC will go to sleep, then wake right back up 2 seconds later. I found out that the KX61 was the problem through trial and errors by unplugging USB cables one at a time.
The Windows powercfg -lastwake did not show any reason for waking up.
The fix was to connect KX61 through a USB hub instead of directly to the motherboard. In this case, the computer was able to remain asleep. I'm not sure if this is a software or hardware problem. Probably a combination of both.
