Here's the setup (also shown above):
- Take a standard USB hub (that's HDMI-enabled) - I used the Choetech one, an early version of which I reviewed here.
- Use the (NexDock-supplied) HDMI cable to go from the hub to the NexDock Touch. This carries all display information.
- Use the (NexDock-supplied) 'Raspberry Pi splitter cable' to go from a USB-A port on the hub to the middle Type C port on the NexDock Touch. This carries all trackpad and keyboard input back to the Lumia 950/XL.
- Plug the flying Type C lead from the USB hub into your Lumia 950/XL. It should recognise a connected display and fire up the NexDock Touch, which is also now apparently happy. Phew!
For bonus points, plug a power bank or mains source into the power input socket on your hub and/or the power Type C of the NexDock Touch. These will top up the Lumia and/or NexDock respectively!
OK, so we have a few more wires than you'd normally need for an Elite x3 (say) or a Samsung Android phone with DeX. But it works!
The bigger picture is that because of Covid-19 logistics and component shortages, the NexDock Touch is effectively terminated as a live product, replaced by the NexDock 360. Of which more later this year. Which is a crying shame. But if you have a 'Touch' (they only made a few thousand) then prize it because it's pretty unique.
