Abstract

External HDD with USB OTG (On-The-Go) Function and Card Reader

Description

Portable HDD including USB OTG and Card Reader {Portable HDD including USB OTG and Card Reader}

USB OTG is a function that automatically detects and performs USB Host or USB Device depending on the characteristics of the USB device connected to the device with this function. In other words, when a device with a simple USB storage function is connected, it functions as a USB host, and when connected to one desktop computer, the product itself is recognized as a USB device.

Most USB OTG-related products still focus on supporting them in mobile terminals such as MP3P and PMP. This allows connection with other small capacity USB storage devices. In particular, it is introduced in HDD-based terminals rather than Flash Memory-based. As mentioned in the above 'prior art document information', there is already a product on the market that supports USB Hub function to external HDD which is a simple storage device.

UP Announcement 6732218:

The present invention relates to an external HDD having a USB OTG function and a USB Hub function.

Patent Publication No. 2000-0002338:

This is an invention regarding a device bay that can connect a USB hub, a USB hub, and a plurality of HDDs.

Patent registration number 10-0402196:

This is an invention of a product that supports a device that combines a flash memory and a memory card reader through a changeover switch.

One of the key tasks is to enable USB HDD and USB Device function by supporting USB OTG function in external HDD. The other will be to support Memory Card Reader through USB Hub function.
