Center console swap with IO3 USB issues

[Chris Stierman]

Does anyone know if it is possible to use a front USB Hub with an IO3 radio?  I've been fighting trying to get this to work all week and I'm getting nowhere. 

 

I had the junk yard I bought my console from cut the body harness side of all the wiring so I have all the stock connectors.   I soldered in the extra accessory power outlet connector and the power for the USB hub to the original accessory power outlet wire. I took my harness out of the jump seat and that is what I am using.   I separated the USB connector out from the loom and ran it to the front of the console. Plugged it into the USB hub along with the 12V power. I then ran a black to grey USB cable from the front hub to the hub under the armrest along with the cable from the jump seat that provides the 3.5mm audio to that and power.

 

What I get is that none of the USB ports work.  The 3.5mm jack works, but none of the USB ports provide any power. If I take the USB/3.5mm module and use it in the front instead of the hub it works perfectly.  If I use the hub by itself it doesn't work.  I think I either have a bad front USB hub or the IO3 doesn't support the hub.  Anyone else tackled this?

Did you do it the same as I did?  It isn't looking good for being able to get it to work.  I tried every combination of cables and couldn't get the hub to work. I tried 2 different USB with 3.5mm jacks and they both work in either place, but as soon as I try and add a hub it stops working.

same as you, hopefully Phil from harnessdoctor will see this post and make a suggestion

@pgamboa  Any ideas?  Has anyone tried using your harness with an IO3?

I haven’t used the usb ports since 2016

 

.5 amps is not enough to charge squat in 2020 and bluetooth works better for audio

Yes. With IO3/IOB systems, you cannot use the factory GM usb cables like in my video.

You’ll have to use generic usb cables from
Amazon. You’ll need two of them.

You’ll have to shave the rubber ends so they fit.

One cable will reconnect under the passenger seat. Other end will go to the front usb hub, in the passenger side port.

The 2nd cable will plug in the “output” of the front usb hub (driver side) and feed the brown port.

Interesting. I thought the GM cables were just normal USB cables with a special connector end on them.  What makes them not work?

They are just USB cables. I meant using the GM usb cables as shown in my video

I can’t speak on your harness build, but customers that have bought my harness with the recommended usb cables have had success in IO3/IOB systems. The “output” of the front usb hub doesn’t send full data, so the console compartment hub only provides charging, whereas the front the USB hub provides charging and data capabilities.

the part about the data capabilities makes sense...i think a lot of people have problems with onboard usb systems because they tend to be very finicky for the reasons you just listed (data/charging). thats something good to point out to people that not every usb is the same and there will be (and are) differences when it comes to technologies.

I spent a few hours troubleshooting today.  I still cannot get the front hub to work.   Either my hub is bad, or the IO3 doesn't support using the hub.  

 

The front hub doesn't work by itself but if I swap it out for the USB/3.5mm module it works with the same data and power coming in. I did try both the passenger and driver USB ports on the hub just in case I was doing it backwards.  I verified I have 12V power and a good ground, which I knew since the other module works in its place.

 

Not sure if I should bite the bullet and order another front USB hub and try again.  I'd really like to know for certain that there is someone who has them both working with an IO3.
