USB Type C to USB 3.0 adapter for connecting

This Koss adapter lets you plug a standard USB 3.0 device into a USB Type C port on a laptop or desktop. It is aimed at users who need to keep using existing flash drives, external hard drives or docking stations after upgrading to a newer host. The pack contains two identical adapters for multiple workstations.

Limited to the 5 Gbps ceiling of the USB 3.0

Data moves at the USB 3.0 specification rate of 3.0 Gbps, so the link will not reach the higher throughput of USB 3.1 Gen 2 or USB4. Power delivery is not supported, meaning the adapter cannot charge the host or negotiate higher wattage for attached devices. Video alternate modes are also absent, so a display cannot be driven through this connection.

Check that your Type C port carries USB data lanes

Some USB Type C ports provide only power or DisplayPort signals and will not pass USB 3.0 traffic through this adapter. Verify the host specification lists USB 3.0 or USB 3.1 Gen 1 support on the Type C connector before ordering. The adapter adds physical length, so ensure adjacent ports are not blocked by the extra depth.
