Hello David,

JF>>> The problem is that, without the hub, I cannot connect both.

Yes you can, with a wireless keyboard and mouse, e.g. my Logitech MK220
does work good with my Pi 3B.
It has an USB2 2.4 GHz dongle for both keyboard and mouse (No BT).
The Pi Zero W has both WiFi and Blue Tooth, so that can be used too for human
input devices.

Does someone know a good BT keyboard and mouse combination that works with both
Raspbian Linux and RISC OS with a Pi 3B of even Zero W?

DL> The (known good) PSU for the hub is switched on and plugged into all
DL> the correct places it needs to be plugged in isn't it?...

I tested a 4 port USB2 hub from Digitus slim spider part DA-70216 on a Pi Zero
(without W) from a fried at the computerclub and that worked ok.

DL> Command lines don't need a mouse...

When started in the desktop,
you mostly have to open/start a commandline window first ;-).

>> Run it headless and leave the screen/keyboard/mouse connected to your
>> your PC.

Does SSH from an other machine not work?

DL> Mr Fearnley doesn't say if it's Pi Zero or Pi Zero W. The former will
DL> need a USB WiFi dongle or serial to USB console cable, or an ENC28J60
DL> based ethernet board to go headless.

With the same friend in NL I tried my Eminent EM110 USB from/to RJ45 EtherNet
dongle too at his first Raspberry Pi Zero (no W(ay)), and that worked ok,
even in combination with the Digitus slim spider USB2 Hub.
That Eminent EM1010 was one of the first USB2 from/to RJ45 dongles that worked
good on the BeagleBoard and Beagle Board XM, both in Linux and RISC OS.
Hopes this helps to get connected with the Pi Zero, or Zero W.

The low price of the Pi Zero flows away, because of the costs of all the
conversion cables to connect it to the outside world,
i.e. micro HDMI to HDMI, micro USB2 to/from normal USB2A, USB2-RJ45 dongle etc.
And then you still have less memory and less speed compaired to a Pi 3B.

Another friend uses a dedicated Pi 1B with Linux for his sunpanel power meting
and to update that info to a website. If configured well, it can run headless.

Henri.
