Update though: I left one plugged in, and after 2-4 hours, my computer starts making the USB connect/disconnect sound over and over for a couple minutes. Was playing a game, so I couldn't tell if anything had happened. Maybe an hour later it does it again once or twice, and the file folder for the pico pops up again. It has suddenly decided to work. Got the program on it, and now it's good to go, behaves normally
If anyone has experienced the same or has theories as to why this happened, I'll gladly take them. I haven't had time to see if the other works now too, but I'm leaning towards it being an issue related to my desktop
