You have 'works / don't work / works / don't work' syndrome.You didn't mention laptop pr PC. If PC try back panel USB port rather than front panel. Regardless of PC or laptop try different ports. Sometimes one port responds 'better' than another.
Also swap USB cables.
Agreed, thats sort of making it difficult to pinpoint, because anything that I think would be the reason for this, wouldn't make sense because at the same time it has worked using the same thing.
I don't have a normal PC, but I did try it on both my laptop and my hybrid tablet, and my friends apple laptop with the same problems. I've also tried 3 different cables as well, but unfortunately no luck so far.
