Strange USB behaviour

My PCs been acting strangely for a while now. The issue is that when I plug in an iPod it appears in nautilus/windows explorer and iTunes for a few seconds and then disappears as if ejected. This behaviour also exhibits itself sometimes when there is 'noise' in the mains. When I say noise, I refer to the disturbance caused by turning on a fan etc that makes an audio amplifier produce a popping sound. I have tried different iPods, iPod cables, and even moving the PC to a different socket and different mains cable to no avail. I'm guessing that the problem's either the motherboard or the PSU. The motherboard is an Asrock k10n78fullhd-hsli. The PSU is a generic one that came bundled with my incredibly cheap case. Hmmm.

I’ve seen the same issue. I would move that usb device to another system and it would work with no issues even if connected to same power source. I would try either a different system to confirm USB as well as trying a usb hub as a mediator. Is there another usb port on the system you can try.

    It could be a bad MB, a bad Power Supply, or a bad wire(the one connecting your USB port to your MB if it is not embedded on the MB).
