Plug USB Directly into Motherboard? - Explained
Hiding USB Devices Inside Your Computer Case
Many computer users are accustomed to connecting USB cables and devices to the external ports of their machines. But is it feasible to connect a USB device directly to the motherboard, concealing it safely within the computer case?
We will demonstrate how to easily retrofit a computer to incorporate this functionality.
Dear How-To Geek,
I was prompted to write after reading two of your recent articles. One discussed upgrading a computer to USB 3.0, and the other covered adding Bluetooth via a USB dongle.
I'm wondering if it's possible to install a USB dongle – or a flash drive, or any USB-based device – internally within a computer. I wouldn't need to frequently plug and unplug a Bluetooth dongle; it could remain permanently connected. Furthermore, those running operating systems from flash drives, such as XBMC or FreeNAS, might worry about accidental disconnection. A hidden internal flash drive would offer greater peace of mind.
Is this achievable? Can a USB dongle or flash drive be directly connected to the motherboard?
Sincerely,
Dongle Curious
The Possibility of Internal USB Connections
In the realm of computing, solutions often exist for those who seek them. Your request is certainly achievable. It is indeed possible to connect a USB dongle or flash drive directly to a motherboard.
Certain motherboards, particularly those designed for server applications, include this feature. This addresses the need to load lightweight operating systems onto flash media, where secure internal placement within a rack-mount server is ideal.
An Example: The SuperMicro X10SLH-F Motherboard
Consider the SuperMicro X10SLH-F motherboard as an example of this server design. As shown in the image below, a blue USB 3.0 port extends vertically from the motherboard's lower edge.
This port functions identically to the ports on the computer's rear panel. Simply plugging in a USB device provides the same connectivity as a traditional case port.
Adapting Consumer Motherboards
Internal USB ports are not commonly found on consumer-grade motherboards. However, this doesn't preclude the possibility of adding this functionality to your machine, provided you have an available USB header.
Referring to the same image, you can see three USB headers located to the left of the USB port: two USB 2.0 headers (black) and one USB 3.0 header. These are indicated by the arrow in the image below.
Utilizing Adapter Cables and Modules
Inexpensive adapter cables or modules can convert these headers into functional USB ports. Installation is straightforward, requiring only opening the computer case and plugging in the adapter.
To convert a USB 3.0 header to an internal USB 3.0 port, you can use an adapter that plugs directly in, providing a vertically oriented port (~$3). Alternatively, a cable-based adapter (~$6) allows for flexible positioning of the dongle or flash drive, particularly useful in cases with limited depth.
Similar adapters are available for USB 2.0 headers. A vertical port adapter is available (~$11), as is a cable-based adapter (~$4) for connecting to USB 2.0 motherboard headers.
With an open header, a small investment, and a few minutes of your time, you can achieve a hidden, internal USB installation.
