I have a power supply from a Huawei Tablet (Output 5V, 2A) and one from an old Ipad Mini (Output 5V, 1A) both with a wall plug and a female USB socket.
ok you need... a male to male cable.
Can I use one of them with a standard USB 2.0 USB A to USB A (male to male) cable?
yes that's the one. usually used on laptop fan bases.
Bought and tried the cable but I have no working UART. So far I have tried both USB-ports on the Micro Desktop, powering with the USB-port of my laptop and with the power supply (Output 5V, 2A). I think that the cable is working because it is new and it can load my smartphone (with an additional USB-OTG female USB to Micro USB adapter). Is there anything else I can try? It is frustrating. Without UART connection I don't know if anything happens at all when connecting the USB cable to the Micro Desktop.
Sorry, forgot to add that I tested my USB TTl to serial adapter with another arm-board and confirmed it working.
