Tom asked this. He is running out of USB ports on his computer. He has a number of USB peripherals and and not enough ports. Is there some way to add new USB ports to his computer?
Fortunately the USB port was created and it replaced the COM port. The COM port was very difficult to set up and as the USB port there was never enough ports to satisfy the peripheral you wanted to use.
The USB is a lot better than the COM port and when you plug in a device it just works. The bad news is most computers have 3 maybe 4 USB ports. And you always want more. When looking for a computer you want to make sure the computers has at least 1 or more USB 3.0 ports. These are much faster than the USB1.0 and 2.0 predecessor.
You can also purchase a USB Hub. These allow you to plug the hub into 1 port and create 3-4 additional ports. You still need to be concerned about the overall performance so if you use a hub make sure it is a USB 3.0 hub and you plug it into a USB 3.0 port. You should also consider devices that don't use USB connections. Many USB devices like keyboards and mice are available using Bluetooth technology. So to save USB ports look into Bluetooth options.
