The older one didn't have anything in /sys/class/typec, but the more recent one did. I was able to use the more recent pre-built image to update the firmware. It looks like the current images should now include the anx7688 driver, so there should be fewer hoops to jump through to get USB peripherals working.

I also double checked whether pinephone-devtools was needed for it, and it looks like it isn't, so scratch that.

Tried the mobian images and still get "i2c read failed" and empty /sys/class/typec. I suspect I borked something while desoldering after all.

Thanks for help anywa.
