How Do I Choose the Best PCI-to-USB Host Controller Do?

A Peripheral Component Interconnect (PCI) to the Universal Serial Bus (USB) host controller is a piece of hardware used to connect devices to a computer. Choosing the best PCI to USB host controller, consider the type of PCI slot you have, as there are several versions that require different types of connections. There are also various versions of USB technology that can be used by the devices you need to connect to your computer, so you select compatible hardware. Different types of PCI to USB host controllers can also provide different levels of transfer rates, so choose a model that gives you a high level of performance.

The function of a PCI-to-USB host controller is to allow the device to be connected to a computer by providing additional USB ports on a machine. A Peripheral Component Interconnect or PCI is a type of connection that can be used on a computer motherboard. This is a column into which different types of internal hardware can be connected. A Universal Serial Bus or USB port can be used to connect various external pieces of hardware. The use of a PCI to USB host controller allows you to insert a card into a PCI slot, which then provides USB ports on the back of a computer.

However, as you choose a PCI-to-USB host controller consider which version of PCI slot you have available on your computer. Many data motherboards have a variety of slots, including both older PCI slots and newer ones such as PCI Express (PCI-E). You must select a PCI-to-USB host controller that can work with the tracks you have available. A PCI-E slot is often used by a video or graphics card, but older PCI tracks can still work well.

Also consider the type of USB connection you want to use. USB technology has changed over the years, with new versions often identical in appearance to older ones. Most of these have been backwards compatible, which means that a USB 3.0 device can still be connected to a USB 2.0 port. However, if you have an older device with a USB 1.0 connection, then it may not work with a PCI-to-USB host controller that has a USB 3.0 port.

There are also various transfer rates that can be allowed through a PCI to USB host controller. Data is usually sent from a device connected to the USB port, through the card, into the PCI slot, and then into the motherboard itself. This means that data transfer speeds are important, as the controller can end up bottlenecks, or slow down, access speeds for the device you are using. Determine the data transfer rates for the devices you connect to this card, and then select a controller that fits them.

  • And USB cable.
  • USB cables are used to connect devices – such as printers, keyboards and music players – to computers.
  • Many controllers are backwards compatible, so a USB 3.0 device can be used in a USB 2.0 port.
