No special driver installation is required except for the SxS UDF driver necessary to recognize UDF formatted memory cards. As it's USB bus-powered, the reader requires no AC adapter. The SBAC-US20 accepts optional Sony ExpressCard adapters for reading XQD (QDA-EX1), SD (MEAD-SD01) and MS (MEAD-MS01) media.
