USB Device/MP3 Player not working properly and can't browse the device filesystem? Check the cable twice and again!

Here is a simple MP3 player and now there's a reason to understand why the supplied cable has some kind of capacitor and is very short.  These devices can be VERY finicky and any voltage fluctuation or difference is enough to cause issues.


Take for example the error messages from Linux Mint:

What was wrong?

It may look like a problem with your device, your OS config or even the USB port but more often than not it was the cable!  I had two three-foot Tronsmart cables, 1 of them worked fine and the other didn't with this device.  The way I found this out was by swapping the cables for fun and also by trying the device on other units.

When a device receives power by a pluggable USB cable you should always stick to the factory cable or use one that is the same length or shorter and of very high quality (even though these thick 18AWG gauge Tronsmart cables have worked fine for other uses!)
