That's good news - I had to 'drop' my Pinephone for a while. Yes, mine connects too now. I just replaced the USB and Mother Board (3GB) which also connects fine on USB2 but nothing on USB3.

The wiki instructs "After swapping the mainboard the ANX chip has to be flashed for full USB functionality"
Download the latest ANX firmware image on the phone: wget https://xff.cz/git/linux-firmware/plain/anx7688-fw.bin
Execute as root ("sudo su") on the phone:
cp anx7688-fw.bin /lib/firmware/
echo 1 > /sys/class/typec/port0/device/flash_eeprom

ash: write error: Operation timed out - Not sure if this is an issue?
