SIIG 2-Port USB 2.0 Low Profile Extension Bracket

The SIIG CB-US0S11-S1 is a low-profile extension bracket that turns the 9-pin USB 2.0 header on your motherboard into two rear USB 2.0 Type-A ports. It offers a clean, permanent way to expand connectivity so you can keep keyboards, mice, flash drives, or other peripherals plugged in without losing front-panel convenience.

Installation is straightforward. Attach the internal 9-pin connector to the matching header, slide the bracket into an open low-profile slot, and secure it with the case screw. Your operating system recognizes the ports instantly, so no drivers or extra software are required.

Once in place, each port delivers data transfer rates up to 480 Mbps, enough for everyday tasks such as backing up documents, loading media files, or running a presentation from a thumb drive. The bracket keeps cables organized at the back of the case, which is especially helpful in tight workspaces or shared desks.

Because it follows the low-profile standard, this bracket fits naturally in slim desktops used for home offices, classrooms, media centers, and point-of-sale terminals. If you are building or upgrading a small form factor system and need reliable rear USB access, this accessory adds the ports you need without adding bulk.

Note that the package includes only the low-profile bracket; systems with full-height back panels will need an appropriate bracket.

• Converts a 9-pin USB 2.0 header to two USB 2.0 Type-A ports
