I have a usb plug in my computer that it is a PIA. The slightest touch or bump or movement and it disconnects then reconnects and sends everything to shit if you are transferring files or whatever at the time. Feels like the plug is just loose to me but never bothered looking into it as there is another plug right beside that I use instead. Anyway a long way to say maybe the plug is just a bit loose, maybe squash the plug a bit to make the fit a bit tighter.
