On occasion, the internal USB hub may stop working correctly. This can lead to your computer not detecting connected USB devices, or your computer may not recognize that the portable display is plugged in at all.
A common fix for these situations is to perform a power-cycle of the unit to reset its internal hub chipset. We've seen that this can often restore the unit back to a working state when one or more of its functions aren't quite working. It's important that the steps are followed in a specific order to ensure the unit’s internal USB hub fully resets. The steps are as follows:
- Disconnect all USB peripherals connected to the portable display
- Disconnect the USB-C power adapter from the portable display if one is present, then disconnect the portable display from the host device.
- Leave unplugged for at least 1 minute for power to dissipate.
- If you’re using PD pass-through, connect the USB-C power adapter to the PD pass-through USB-C port of the portable display
- Connect portable display to your host device using the included USB-C cable, then connect USB peripherals and test for functionality
