USB host on Pico- do we need a host controller chip ?

Hi Simon,

I'm afraid nothing has progressed on USB Host. While possible with the hardware (although I think most implementations add some kind of USB switch device?) there'd be a lot of software work required in Espruino, and that hasn't been done.

So I think your main options would be:

• There is a MicroPython port for the Pico (I'm not sure how old it is) and that may support USB Host - at least MicroPython supports it on their own boards.
  
• You could write the code you need in C using ST's libraries - depending on what you're after and if there's an example already that may actually be the easiest option
  
• There's the external shield option - but that could still be a decent amount of work
  
  

Sorry to not have better news!
