Gemma flashes red LED at random?

by eram1294 on Sun May 22, 2016 6:53 am

When I plug my Gemma in (battery pack or USB) the red LED flashes seemingly randomly and will stay on solid for short periods of time.


Additionally it has not been recognized on 4 computers I have tried to program it with (1 Mac OS X Yosemite, 1 Windows 7 Professional, 1 Windows 7 Home Premium, 1 Windows 8). I have followed the instructions for setting up the Arduino IDE and setting up the Board Manager and downloading the drivers, but it has not been recognized. I have been connecting it with the USB cable included in the starter kit that I purchased. Have I missed anything? Thank you.

Does the gemma appear in Device Manager (Windows) or System Report (Mac)? If so, what is it listed as?
Possibly your USB cable is defective. Do you have some different ones you could try?
