Quote:USB-C CC pins are grounded when VCONN switches are off
I discovered that all the current PP variants (1.0–1.2, Braveheart and at least a part of UBports CE batch) have a major issue, that prevents CC pins from working correctly. This issue will be fixed in revision 1.2a by a component swap.
Further up the page there's mention of a problem with PD chargers (and docks that do PD) but that appears to be due to something that's not yet implemented in the driver, not a hardware issue.
