Ramps causing issue with computer.

So to day I installed my ramps 1.4 into my laser cutter and everything works flawlessly except when I use my 8 ft USB. At the moment i have a 1 ft USB which connect to Pronterface, but when i try the 8ft i get this error.


So at this point I thought it was my arduino mega board, but after unplugging it from the ramps the board was able to connect to the computer no problem. To add i did remove the D1, because my laser runs off 24V.


Here a pic of my device manager


Thanks for the help!!!
