I purchased this item to provide an Ethernet port to a Pi Zero (non-W model). Once plugged in it works out-the-box with the latest version of Raspberry Pi OS (previously Raspbian). The USB hub also allows a keyboard to be plugged in without using a microUSB-USB adaptor.
Was searching for a cheap item that would expand connectivity of pi zero - this works perfectly. Was well pleased when I could get on internet and plug in USB mouse & keyboard with no extra power required.
