The most likely cause of this is a failure of the device manufacturer to adhere to the USB specs. USB-C (or maybe 3.0 or maybe PD) requires some resistors on the data lines for power negotiation. Even when you just want low level 5V at 0.5A you’re supposed to have some specific resistors to tell the upstream power provider what you want/need. Previous USB power didn’t require this and a bunch of devices that were designed for micro usb were updated to C connectors without revisiting the power circuit. As a result these non-compliant devices can’t pull power from compliant power supplies and computers. Options are to use the “special” cable (which is almost invariably a USB-A to USB-C cable since non-C ports provide 5V at 0.5-1A continuously) or to use “dumb” or otherwise non-compliant power supply (non-PD compatible power banks for example might still supply current on the USB-C out)
And yes this is stupidly annoying
