Compatibility test list

Feel free to edit this list and add your test results.

In the list below, the columns have the following meanings:

• PD: KXUSBC2 was able to complete Power Delivery negotiation (ending with PS_RDY)
• QC/HVDCP: For USB-A sources: KXUSBC2 was able to request a higher voltage (e.g. 9 or 12 V) using QC 2.0/3.0 (also referred to as HVDCP)
• BC1.2: For USB-A or non-PD USB-C sources: KXUSBC2 was able to charge at 5 V / 1.5 A or more

The KXUSBC2 performs QC/HVDCP negotiation only when acting as a sink. When acting as a source, it only does PD or BC1.2.
