... I believe that digital cameras all come with a standard cable that has a regular USB port on one end and a Micro USB port on the other. I've used the same cable for my Olympus E-M5 and E-P5 cameras with no problem.
Not so!
The connector on the camera side is Olympus proprietary, NOT standard 'Micro USB'. Standard Micro may be found (emong others) on some Nokia phones, on Amazon Kindle reader, etc.

I agree with jnewell, get an Olympus or another high quality cable. I believe that digital cameras all come with a standard cable that has a regular USB port on one end and a Micro USB port on the other. I've used the same cable for my Olympus E-M5 and E-P5 cameras with no problem. If I am wrong I hope some more knowledgeable person will speak up to correct me.

PS, to be safe you might want to call Olympus Tech Support.
