Thinking to run a Rpi Zero USB hub without power for a Huawei internet stick and a USB to ethernet adaptor for SSH connection to laptop. Will the RPi zero be able to support these two devices at the same time? No other device will be connected at any point to the hub. Can i avoid using a powered USB hub? Cheers!
Not sure if this answer's your question, I have been able to run raspi-zero with usb-3g-internet without any hub. In my case, i dont see the need for second usb. I am able to communicate with my raspi using xmpp/jabber protocol. After linux boot, my raspi runs umtskeeper script to connect to the internet, after that it runs a gloox-C++ library based xmpp chat client daemon. I see it on my android phone's xabbere app when my raspi-chat-client becomes online. I send chat messages to my raspi for controlling gpio's and other remote control commands. The details of this setup are given in my blog. http://albert-david.blogspot.de/2016/09/rbox-raspberry-pi-zero-usb-3g-internet.html
