Abstract: In the application of many digital products, there are common problems that PC Universal Serial Bus (USB) connectors are relatively insufficient and each digital card matches to its specific reader. To solve these problems, the chips of FE1.1S and AU6437 are used to design a set of multi-function USB hub which includes a connector of SD card and micro SD card, respectively, and two standard USB connectors. After testing, the hardware of this design has perfect functions and stable performances, which meets Universal Serial Bus Specification revision 2.0. It is believed that this study provides some references and proofs to the design of multi-func tional high speed reader.

Key words: USB hub, FE1.1S, AU6437, SD card, micro SD card
