The Sony SBAC-US30 USB 3.0 SxS Memory Card Reader is recognized by PCs as a "Mass Storage Class", so no special driver installation is required except for the SxS UDF driver needed to recognize UDF formatted memory cards. The SBAC-US30 is powered by USB 3.0 bus, so no AC adapter is required. The SBACUS30 card reader is also USB 2.0 backwards compatible.
