There are only two USB on the notebook, and there is no place for the USB flash drive after plugging in the mouse and camera. Bringing a USB Hub is much more convenient.
The usb interface of the desktop is usually at the back, and it is tiring to bend over to and unplug. Connect the USB Hub to the back, we can use the usb device directly in front of the host.
Using high-speed chips, high-speed, high-capacity memory cards can be read.
No driver required, and play, support hot swap.
