Hello,
1. Please note that the hub cant initiate suspend for the host as per the USB specification but it can enter deep sleep mode to save power if host initiates suspend. Please refer to the macro SYS_DEEPSLEEP_ENABLE in the HX3PD DMC and PD firmware.
2. Yes, the power supply can be turned off for DS1 using the psrc_disable() function to disable the VBUS provider path in the HX3PD PD controller firmware.
Best Regards,
Sananya
