USB Device connects and disconnects after a few Seconds

I suspect that the port itself is the issue, and not supplying enough
power/voltage. may be problems with the motherboard or the powersupply
of the PC. You may try disable save power in Device manager for the USB
hub but likely that wou't fix the real problem.

How good are you with a VOM? If that term is unfamiliar, you are better
off using powered hub, if that won't work for you, try replacing Power
supply and if you still havent got it working replace the motherboard.
