Troubleshooting
Power Supply Consideration
The UH3239 USB-C Multiport Mini Dock requires a total of 15 W power
consumption from a dedicated power adapter, and then provides balanced
power supply to the connected USB-C host device with the rest of the power
supply.
When the total of power consumption of the UH3239 exceeds 15 W, a self-
protection mechanism is activated, and some of the connected devices
(excludes USB-C host device) may not be found.
iPadOS Limitation
For iPad USB-C enable tablets power delivery, make sure to upgrade its
iPadOS version to iPadOS 13.2 or later to meet the power delivery standards
for iPads.
