DOH! I wish I read this forum entry before I bought my Genuino 101. Why?
Well I had the same problem with a CurieNano.
Got no help fixing it.
Tried different computer, bought fresh data cables, tried all USB ports etc.
Assumed I got a dud CurieNano so bought a Geniuno 101.
Same problem with the Geniuno 101.
The problem is in the IDE/Drivers for sure.
I can get the chip info so the IDE can see and talk to the board, just cannot load software onto it.
DFRobot admitted they had seen the problem. But when I went to negotiate a return on my CurieNano board DFRobot appeared to require me to have "different" problem to be eligible for replacement. I think there is a real problem here no one is admitting to.
I actually have USB 2.0, tried manual install of drivers.
All hale Intel. There used to be a thing called Wintel you remember? I note the same problem turns up on Linux. That is therefore a bug in the IDE OR we are being sold dud boards.
Has to be one or the other.
Has anyone been given the suggestion to download the firmware source, build and install? Don't, you will do any warrantee on the boards. My view is I bought a functioning board not just chips soldered to a board - which is all I have at the moment ... twice over.
