OSError: fusion hat driver not loaded

General
1

I’ve been doing Paul’s courses without issue for the first 8 courses. When I turned the pi-5 on and started the 9th, I get an OSError, fusion hat driver not loaded.

I have already re-flashed my SD with V1.0.0 with the same results. Other issues are the homework assignments from prior will not work and give the same error. I am also missing the orange charge LED on the hat now. I did not update, and this second copy doesn’t even give me the icon on the taskbar.

I’ve searched other posts similar and they seem to abruptly end without revealing the issue.

running fusion hat doctor fails I2C MCU(0x17) sysfs interface.

Did my hat go belly up?

OK, little odd but I held the pwr and USR buttons and I now have the orange LED illuminated, so I tried 'fusion_hat enable_speaker" and it accepted it without problem. I tried “fusion_hat test_speaker” and it ran just as it was supposed to.

I would try running my homework programs, but alas, they are history because of the reflash.

I modify my issue to : What happened to turn my orange LED off?
