Seems like it's really easy to diagnose - problem with comms over a cable? 1/ is it seated correctly, 2/ are there any obvious defects, 3/ are the specs of the cable and the ports aligned?
Having incompatible ports means 3/ disappears but since many cables support multiple specs, it's nice to often have a win when connecting two devices over a cable rather than simply being blocked because the connector isn't compatible physically.
- happyopossum 4y ago> 3/ are the specs of the cable and the ports aligned? This is basically impossible to diagnose as ports and cables are not marked with their supported specs.
- pbronez 4y agoHDMI has the same mess. Ports don’t tell you much.
- mmis1000 4y agoThere are actually dedicated detector for detecting charger compatibility or faulty cable. And they are surprisingly not that expensive (rage from 20 to 40 usd depends on spec and vendor). Something like, test the cable and get a resistance of 0.6Ω ? Let's just toss it away. This will definitely fail the usb protocol and stop devices from working properly when charge at full speed. I actually found a few problematic cables with that. These are pretty hard to find out normally because they only fail when charges at full speed (cause the voltage to drop too much) and transmits data at same time. Or test a charger that labels fast charging but don't actually get any at all? The resistance changes a lot when you touched the cable(probably the connection between board and plug breaks)? Toss it away. They are broken or fake, why bother keep them.
