KC868-UAIR ESPHOME Config for IR and RF

[dmshimself]

can you change a USB cable or connect to another USB port, maybe low voltage of power supply 5V.

I've tried 3 known to be good USB cables and I test them using a USB Disk drive.  The cable that was delivered with the KC868-UAIR itself doesn't work with the USB drive and also doesn't show any information back when I do an lsusb with the KC868-UAIR plugged in to my laptop, so I don't use that cable.

There is no other port I can plug into on the KC868-UAIR as the left hand USB port is for connecting additional modules.  If you mean a different USB port on my computer, I've tried other ports and get the same result.  In testing though I don't use the USB on my machine to provide power, I use a 5W Apple charger.  I've also used a 1A charger for a raspberry pi4 and a 1A charger for a Samsung phone.  All give the same result with all the 3 known good USB cables.

Some more information if you suspect a power issue:

I can turn on both sets of lights on the device as well as the buzzer all at the same time and they work.  I would have thought the IR receiver I'm testing would need far less power than those devices?

I can upload my ESPHOME config to the KC868-UAR with wireless and again I would have thought that wifi would use far more power than the IR receiver?

Do you know of any other way of testing the IR and RF?  I could use an Arduino sketch for testing - ultimately though I want to use ESPHOME as this is one of the advertised interfaces and the Arduino interface that used to be supported by Home Assistant is no longer supported.
