I checked the forum but didn’t find exactly the same problem. I just picked up a second-hand Organelle m. Worked fine, updated to latest firmware. Didn’t have the usb wifi adapter, so I was loading all patches via USB stick. All worked fine but suddenly, all USB it stopped working. I tried reformating the stick, reloading newly downloaded patches, re-installing firmware, and still nothing. I tried 4 different USB sticks that worked perfectly fine on other devices and did it in both slots. I live in France and not sure what to do next. I thought maybe one of the slots failed but both at the same time?
Edit: I wanted to add I opened it up to check the USB slots’ connection points and all look fine.
Edit 2: I tried to run the test in utilities. The USB slot does detect the keyboard so I’m not sure if it’s related to anything physical with the USB slots then? I did also try to re-burn the latest OS on two different micro SD card, the original one at 8gb and another Sandisk one that is bigger. Still same result, when I try to load the USB stick its as if nothing is plugged. Please help if someone can!
