Hi @matthewchen, sorry to hear about your issues. The first thing I would suggest would be to ensure you have installed the latest version of the USB Chipset and BIOS for your system and of course fully updated Windows 10.
Can you confirm if this behaviour is persistent on other USB ports also? It would also be a good idea to look at your power settings in both the device manager of the USB hub in question (and in general Control panel settings) to see if the power to the 4C is being reduced automatically.
Please go through these steps and let me know how you get on. Best Wishes.
