OTG hubs

Micro USB (OTG) connection

— microUSB is a smaller, mobile version of the USB standard, which is found in the vast majority of smartphones, tablets, and other portable devices. Usually, all these devices can be connected to a computer in managed mode, which allows you to copy or write information, make a backup copy of data, etc. But devices that support USB On-The-Go (OTG) connections allow the ability to connect in host mode — when peripherals like the same flash drives, external hard drives, etc. are already connected to a smartphone or tablet. In other words, a card reader or USB hub with microUSB support (OTG) can be connected to work with a smartphone or tablet that has USB-host mode.
