Hi - I use the Raspberry Pi Camera (v1.3) with my RP3B+ on my Prusa MK3s and it's been working great.
I decided to try adding a touchscreen and running the touch UI plugin on it. I got the Jun-Electron 3.5" TFT from Amazon and installed the drivers from here (https://github.com/goodtft/LCD-show) via PuTTY/SSH. The screen turns on and works great, but I no longer have a functioning camera. I SSH'd in and do an "lsusb" as troubleshooting suggests, but no camera is listed.
Any ideas what I should check to see what might have happened? Physically removing the touch-screen doesn't change anything.
I'm running OctoPrint v1.4.0 and OctoPi 0.17.0
