USB device and its symbol!
I don’t know how many times I plugged my USB devices wrong in my computer. How many times I tried to force them in and then had to bend on the computer to see which way is the right way for plugging the USB. The symbol which is on these devices is in a different side. One has to face up so it can be plugged in; the other has to face down to be plugged in. Plugging a USB device in a computer is trial and error. Plug it in, it doesn’t fit? Turn it around and try again! It would be nice if all the manufacturers could follow the same rule, put the symbol on the same side and prevent users from damaging their computers’ USB ports.
