So I've been working on a school project for the past couple weeks, and I've programmed over usb to make it the process easier. Everything was working fine for a solid 2 weeks until the system crashed and now both my laptop and my desktop won't detect the raspberry pi on my device manager. It doesn't show up as a port, or a usb ethernet/rndis gadget. I've tried flashing a new image and modifying the files needed for the setup (config.txt, cmdline.txt and ssh) so that's not the problem. I also reinstalled all the drivers (port, universal serial bus controllers and network adapters). The raspberry pi still works fine, I connected it to a monitor with a mini hdmi cable and i've connected a mouse/keyboard so the usb and power port still work. I've run out of ideas :( And both my computers are running windows 10.
