I've played around with the ProMicro somewhat and being enthusiastic about de capabilities of this tiny device, I ordered some more. The recent models have even smaller dimensions along with a Micro USB connection, where the others had a Mini USB socket.
Now... I connected a few components in the same manner as I did on the older ProMicro which worked fine.
I had connected the pro micro directly by USB but my laptop gave an error message that the "latest connected USB hardware was not working propper."
And no... I could not upload my sketch.
My laptop did not even see find the right USB port.
Knowing it might have something to do with a bad connection, I desoldered every component whilst testing every step. No success or whatsoever.
Finally, I took another ProMicro and that one did connect correctly... For a brief moment.
My system noticed a Lillybit(?) device connected, but then also... The USB connection was lost again.
I've tried several USB cables on both devices. No effect. The power is on, which can be affirmed by the green onboard LED.
Did I blow something up? I mean... If it has a USB connection, I assume I can hook it onto a USB cable from my system, Right??
Then what is it that causes the devices to die on me...?
Oh, worth mentioning... The second device died even before I managed to upload any code.
Anyone on this??
