Tom,


Can you take a look at the contacts on the USB end on the one that isn't being recognized and see if the might be a bit off center compared to the other - I'm wondering if the data contacts (the two middle ones) aren't lining up quite right and maybe you got lucky and they lined up on the first try.


Otherwise have you done anyhting with it besides programming it once?

Attached a photo of the one that doesn't want to respond.
The contact look lined up to me.

So no response at all - no USB connected sound, nothing if you wiggle it a bit? But the power LED comes on correct?

Yes, the LED is on.I don't remember what sketch on it, but it involve blinking and maybe a try to communicate with it through a terminal.That's all.

Tom,


If you can provide any more info on what sketch you may have loaded - ie was it an example, was it a Digispark example or a stock Arduino example, etc, etc I'd like to make sure it wasn't related to a sketch somehow corrupting the bootloader - though I really doubt it as I've tried to do that and haven't been able to.


Otherwise it sounds like it might just be faulty - send me an email and we'll take care of you. support at digistump dot com
