I have a Raspberry Pi Zero and I setup the SD card like described here: https://archlinuxarm.org/platforms/armv6/raspberry-pi. I wanted to connect a USB keyboard to it and attach a monitor through the HDMI mini port. The monitor works as expected but the USB keyboad does not. First I tried with a micro-USB to USB 2.0 Adapter (I tested it on my Android smartphone there it works) but the keyboad does not work. Then I ordered a special adapter, where I could also connect a LAN cable, this one here: https://secure.reichelt.com/ch/en/raspberry-pi-zero-network-converter-3-port-usb-hub-white-r-rpiz-multi-hub-p223619.html?CCOUNTRY=459&LANGUAGE=en. As this one is used quite often with Raspberry Pi Zero as I have read I hoped that would just work out of the box but it does not.
What do I need to do to get a USB adapter working? Also the LAN connection does nor work, would this work as soon as the adapter works or is there also something special required to get it working?
