Hi everyone,
I've been working on a project for controlling a robot and have a pi4 4gb that serves as a dedicated control center for the bot. It includes two picos, 4 rotary encoders, two 10-led bar graphs, and four key switches. All this hardware is basically split up between the two picos.
I've noticed if I turn on the pi, and plug in those picos to the usb ports, everything works. However, if I shutdown and boot back up, one of he picos isn't working. If I unplug it and plug it back in, it's back to working. While it doesn't work after boot and before unplugging, I can still see it in my file explorer/file manger(not sure the term for linux) and I can also see two devices connected when I run lsusb in the shell.
Any thoughts what's going on and how to remedy this? I should add that my project is lipo powered but even with a wall adapter with usb-c (pi issue), I have this issue. I thought maybe this was a power thing related to that but doesn't seem to be.
