So I bought an RF-NANO, an arduino nano combined with an NRF24, from Aliexpress, and it wont turn on when I plug it in at the USB port.
Heres the link:

The voltage directly at the USB port (between +5V and GND, directly under the USB) is 0. When I use the same cable and a different nano, it turns on, but I tried a different cable anyway, and it didn't help. The nano turns on when powered through VIN, however still does not show up on the ports list. I have checked for continuity in the USB pins, and GND is connected, D+ and D- are connected to the CH340, and power from the USB goes to the middle pin of the regulator. everything appears good, but it is not working.
Any help would be greatly appreciated.
