1) Is the hardware fix applicable to BH phones?
2) If yes, what are the necessary steps to enable OTG on the software side? After removing the regulators I tried bott the nightly Mobian and PMOS ANX image and only get stuff along the lines of "anx7688 0-0028: read failed (-6)".
I did the hardware mod on my CE Pinephone a few days ago. I haven't fully tested all OTG functions since I don't have a USB-C dock right now, but I was able to get a USB keyboard and mouse working in Mobian after I:
1) Installed the updated anx7688 firmware (for me, this got rid of the anx7688 error message I saw when watching dmesg -w). The process for this is described on the xnux.eu page about the Pinephone hardware bug.
2) Installed pinephone-devtools (I'm not 100% sure if this is required, but I'm pretty sure I was having issues with peripherals still not working until I had installed this)
