• hi,
    I am trying to input data to a pico from a USB barcode reader (in either HID or virtual com mode).
    OTG is not required , USB would be a dedicated input.
    Happy to dig deeper and get a logic analyser on the case but USB low level signalling is a new world for me. Searching the forums :

    So my questions here are:

    • has anything moved on since the above conversations with USB peripheral input to the pico?
    • is there any way forward to ustilise the USB host functionality of the STM32F401xD ?
    • is an additional host controller chip/shield the only practical way to crack this? Seems a really unnecessary overhead if the STM.. can handle the host interface.

    and any suggestions on investigations I could do to move this forward appreciated.

    Thanks in Advance
