Hi, I bought a new Lenovo Flex 5 laptop a couple days ago, and it comes with 2 USB 3.0 ports and a Type C port. I have lots of USB 2.0 flash drives which have stuff from my old computer, and I tried putting them into the USB 3.0 ports, but they just won't fit. And yes, I've tried flipping them too. The USB ports seem like they're a little pushed inside, but when I insert something in them, it reaches the ports, but doesn't go any farther. I have checked all over the internet too see if USB 2.0 devices work with 3.0 ports and it says they do. Help please
