The CSC1220 innovative designed make used of the up-to-date USB-OTG technology to perform a MP3 player slim and embedded memory free. It can accept any kinds of USB storage devices compliant with Mass Storage Device Class via the embedded OTG module, e.g. USB flash disk. The media now can be accessed with free of internal memory, you can enjoy the MP3 free and direct via various kinds of resource now. About USB-OTG USB OTG is a new supplement to the USB 2.0 specification. It challenges the capability of existing mobile devices and USB peripherals by giving them an added host capability for connection to other USB devices. These new features were needed to upgrade standard USB technology for mobile, peripheral devices and gateway bridge. These new features include the additional host capability, smaller connectors, and low power output, which eliminate the current limitation in the USB that requires a PC to act as host.
