Just got my new EM1mk2 and love it.

One of the things I want to use it for is to take astro shots and need to control it with Olympus Capture running on my laptop..

The issue I have is the USB cable provided is very short, less than a metre.
Is the socket on the camera USB-C or is it Olympus proprietary ?
Can you get longer cables? or do I need to get a Hub.

You can get USB extension cables, that would be your simplest solution. They come in a variety of lengths and some have signal amplification. Amazon have several for example. I'm not sure if the Oly connector on the Mk2 is proprietary, it is on my E-M5 and XZ-10. If you keep that cable though you'll have the benefit of the correct filter at the camera end.

On Page 10 of the full manual the socket is described as
USB connector (type C)

it is not like any other USB connection I have seen before <g>

USB-C is the new standard. In a few years all USB connectors will be like this. You can plug the cable in either way round and it supports USB 3.1. So the cable is standard, not proprietory.

You can buy longer cables easily, this is better/more reliable than buying extension cables. Here is one from Maplin:

Thanks but the product you linked to is discontinued.

You can easily search for one. You need USB-C to USB-A.
Here are some - this one is 2m:

This one is 0.9m:

Because USB-C is still new, the cables are quite expensive. That will change.

I use a 3m USB extension lead with the camera tethered to the laptop, it works perfectly.

I bought one made by Belkin as they are good quality products

Agreed, and how refreshing to see a move to standard connectors rather than proprietary!

I wish they would do that for power as well. That's the one socket that is missing on the body,

Didn't know that the EM1 had USB-C connector.
As a note of caution cheap USB-C cables can cause serious damage to equipment so don't race to the bottom of eBay etc. for a deal or it could be a very expensive mistake.

There is a Google Engineer, Benson Leung who has been testing and shaming non-compliant cables. He managed to fry his Chromebook with one!

I don't know the veracity of this site but it would be worth cross checking before you purchase a cable and connect it to your brand new toy!

This Wikipedia article (https://en.wikipedia.org/wiki/USB-C) suggests compliant USB-C cables must be 1m maximum. The tiny dimensions of the 24-pin connector seem to me to be asking for trouble, especially as the article claims power currents of up to 3A are permissible! USB-C is a new one on me and I'd no idea it was so complex compared to normal USB.

The article also says this:

"Some non-compliant cables with a USB-C connector on one end and a legacy USB-A plug or Micro-B receptacle on the other end incorrectly terminate the Configuration Channel (CC) with a 10kΩ pullup to VBUS instead of the specification mandated 56kΩ pullup, causing a device connected to the cable to incorrectly determine the amount of power it is permitted to draw from the cable. Cables with this issue may not work properly with certain products, including Apple and Google products, and may even damage power sources such as chargers, hubs, or PC USB ports."

Caveat emptor I guess. In the meantime, based on that Wiki article I'd seek advice from Olympus about using an extension cable; better safe than sorry.

My android phone uses a USB C to A or A to C if you must and longer ones are easily available be sure not to get a cable for a fast charger as they are C to C.
