My experience of USB connections via hubs is that they can be AWFULLY flaky. So, this needs to be kept in mind if updates must be by a direct connection to the computer, ior, internet rather than via a card.

However, best practice for this kind of update is NOT to destroy the current version until the update is complete AND the system has been re booted.

This can be done by booting via a pointer to the active system. The VERY LAST THING the updating s/w does is to change this pointer to point to the new systems.

All the other comments about check sums etc. of course apply, however, tricks like this date back at least to the late 1970's. It's now 2017!

I didn't chase this completely, however, I found this page

https://www.olympus.com.au/Support/FAQ-Trouble-Shooting/Digital-Cameras/What-can-I-do-if-I-could-not-connect-my-camera-wit

It contains this warning..

"Caution:
Computer may not be able to recognize the camera when you use USB HUB for connecting camera and computer. Please note the use of USB HUB is out of operation warranty. Please try connecting camera and computer without USB HUB if you currently use it.".

I'm not sure if it relates to the OP's problem, it IS worth keeping in mind.

Definitely worth noting, however my failure was with direct USB connection to my microsoft surface book's USB connection using the cable which was supplied with the EM1 mk2.
