you should prepare yourself with ground loop adapters.
Nooo, no more adapters please! 
I just realized the hum disappears completely when I unplug the usb cable from my Digitone (or the Digitone from Overhub)ā¦ When I connect the Digitone directly into my computerās USB port, thereās also no humā¦
So maybe it has really something to do with Overhub itself? 
i think it has to do with different pieces of USB power in the chain.
itās the best way to get rid of the noisefloor

my problem seems to be solvedā¦ after looking for the main source of the hum, I found out that Iād accidentally connected two devices from midi in to midi in, when I was re-arranging my āstudioā recently. I now have swapped it from in to out and the hum was gone. all good now 
hope that will help someone someday, haha

Cant use it, canāt find a propper power supply in Germany.
Why didnāt you communicate this in the merch?
I bought a (brand new) Overhub a few days ago from Andertons in the UK. Fresh out of the box, only three of the seven USB ports work with my Rytm MkII / Digitone.
Iām guessing I got a dud unit and should just return it, but thought Iād post here first in case: a) someone else has had a similar issue, or b) Iām just doing something stupid.
Assuming itās broken, and given the number of issues people here have had with the Overhub, I guess I should just return it for a refund?
I raised a ticket with the good people at Elektron and they kindly shipped me a replacement Overhub.
The replacement is a v2 unit - different design, packaging, slightly lighter.
Seems to be working well so far.

Iām buying a power supply for my Overhub, lets see if that solves the issues i have? Currently just doesnāt show the multiple Elektrons hooked up to it ( ! ) Possibly because iāve got some extra external drives hooked to another hub, which in return is maybe draining too much power away from the regular USBs on my Laptop for the Overhub to properly communicate? Would be nice for a change if i didnāt have to constantly fix stuff with stickytape in order for it to work, or unplug stuff in my minimal setup. Time to whip out some commercial shitty tunes as to aquire myself some proper hardware?
My Overhub stopped working. There is still the green light that is lit but without disconnecting anything, it just stopped working. I tried different USB ports, no joyā¦I paid so much money for it as wellā¦unreal.
My overhub also stopped connecting after a year. Itās utter trash. I opened a support ticket and they offered 50% discount on a new one. What a joke! They should fix the issue because itās pretty clear after reading this thread they havnāt dealt with the issue yet. Iām never going to buy a new one and am very disappointed about Elektron putting out such a bad design. And itās not like theyāre cheap either. I thought I was buying Elektron quality.
Has anyone had issues with Overhub Rev2? wondering if the wobbly USB port is Rev1 only?
i wonder the same.My rev2 arrived today.Works good and looks sturdy but the connections seem quite sensitive.I have 3 Elektrons plugged in and a Soundcraft mixer and if you just touch this thing there is a danger it will lose connection to my soundcraft.Not sure i`ll keep it.Still a few weeks to try before i return it or not.
My Overhub (my second unit) stopped working / being recognized by my Mac Pro/Macbook Pro/Macbook Air a while ago. Today i just gave it one last try on the MBP, connected 2 devices to it and started checking / refreshing system report. One of the devices, the SH-01a, powered up, yet didnāt show up as midi device. No USB devices were recognized by System Report anyway.
As i went to register the device / file a support ticket, all of a sudden my Macbook reports i should disconnect devices that are taking too much power. Same time i see that the SH-01a stops working and when looking at the Overhub i see smoke coming out of one of the USB portsā¦ Another chapter in the drama i call the Overhub 
ufffā¦itās so bad when just a hub can kill your USB periphals or cause some real danger.
i would go for the Anker one as theyāre bulletproof with intelligent power distribution and such.
did someone pictured a teardown on overhub yet?
maybe to find a similar board and/or issues from other manufacturers
Did you use it with a power connector?
I think faultless use without a power connector is only guaranteed with overbridge devices.
Totally unsure what USB hub to get after reading this thread.
Thinking of maybe just trying something well rated from the big A and safe a couple of bucks while doing so, especially as they have a power supply included.
Though I want to avoid risking any overbridge problems with the third-party devicesā¦
What do you guys think?
Here are the ones I looked at:
Iāve never used overhub so cant comment, but I use a powered hub by orico which I got via amazon for like 30 quidā¦Iāve not had any issues so far with using OB controlled boxes, or with push, my usb midi - cv box+merge module, OB6.
Are you using it with Overbridge?
Yeah, so far no issues.
@Rumscheid303
should be fine with USB 2.0 OB devices, but since it uses a VL812 chipset (single transaction translator), MK1 Analogs may present issues with that ORICO hub.
Yea, just to be clear thus far Iāve used the ARmk2 and currently the DT and both work as expected. Have not used any mk1 units so worth checking before hand.
