My computer makes the usb disconnecting sound whenever I use my sewing machine (that is in no way hooked up to my computer)?

It's not a huge problem, I'm just super curious as to why it happens. Ever single time I press on the foot pedal to my sewing machine (only while it's on, obviously) my computer will make the noise like I unplugged something from the usb. It never makes this noise any other time (besides when actually unplugging something from it xD) but it will do this every single time--ever little 5 second pause, as soon as I step on the foot again it'll make the noise. My sewing machine is just a cheap starter machine and is in no way connected to my computer, nor has any ability to.

    This is a sign of bad wiring in your home. The two devices are on the same circuit, and when you depress the pedal the computer is detecting that it's not getting enough power. On a modern machine, the computer will shut down nonessential components like internal USB hubs and firewire ports to maintain operation. This is part of how it protects from power dips damaging components.

    The motor of the sewing machine is generating a static that's interesting with a mouse a keyboard or other wireless device

    Put the computer to sleep!
