The USBHub3c defaults to supporting BC1.2 (SDP and CDP) and PD modes on ports 0-5. The USBHub3c Quick Charge feature adds the ability to enable the Quick Charge (QC) version 2.0 and 3.0 port mode on one or more ports. Qualcomm® Quick Charge™ enables fast charging on supported devices. This software license is associated with a specific USBHub3c serial number.
Quick Charge support includes QC 2.0 and 3.0 support with data line negotiation. By default the USBHub3c supports QC 4.0+ by allowing the USB Power Delivery Standard Power Range (SPR) which is the new programmable power supply (PPS) mode for charging voltages from 3-22V in 20mV increments.
Note: Enabling Quick Charge mode on a port will disables USB2 data lines on that port since these lines are used for QC's protocol.
