Hello, i have an Dell Inspiron N4010 , is it possible for me to replace the USB 2.0 port with a 3.0 port??
It's possible to replace USB 2.0 with USB 3.0 for desktop if you really want to gain USB 3.0 speed. You could try this, upgrade both your USB ports and card readers slots to USB 3.0.
But for your laptop upgrading, i am sorry i could not help too. 🙁
