USB-C CC pins are pulled to the GND by AW3512 (VCONN switches) when VCONN is off

Please download either PMOS, Manjaro, KDE, or Mobian factory test build from wiki site, dd to microSD and boot up. During boot time, OS will flash new ANX7688 firmware to ANX7688. Just complete boot up will do, there is no need to performance factory test or flash build to eMMC.

Thank you.  I downloaded recent PMOS and KDE images, but found this didn't occur even though it should have.  So I followed this technique and it worked based on the output of the update process:

Once the firmware was updated, I found that the I could use the dock, Pine keyboard, and an ordinary mouse in PMOS fine, but that's not my target.  

In UBports, these devices continued to not work.  I then found that I could update the kernel through UBports' system settings and switched to that from the development branch.  This updated the kernel from 5.6 to 5.10 and the anx7688 chip now shows up when I check with dmesg.  However, the hub and devices still remain undetected and the anx7688 module shows "0" with lsmod.

So mostly there, but same general outcome.
