it has “Genesys Logic GL3522”, which should have MTT according to their website.
If only it had a CF reader instead of 4(!) SD readers 
this one too

.
but tbh, my £6 MTT one with USB3 support seems to be fine
a very smart powered hub with 7 ports is gonna suit more folks, but it’s only usb2, so no good for your faster drives it’s also usb3
^ was just gonna post I noticed overdub in the vid… I want it because it’s shiny 
(and I haven’t bought a dedicated hub yet) wonder what the tags gonna be tho?! 
edit - I mean overhub but overdub is good too.
I have this one which is similar and MTT
I just started testing today so take it with a grain of salt. I have a Rytm and Analog keys and it was being finicky when trying to enable max channels for both units. Seemed I could only get about 8 or so channels working together simultaneously between both devices. So if you are not looking to max out or just have one device it should be fine.
My OWC Thunderbolt 2 Dock seems to rock the socks as I can do max channels on both devices simultaneously. I have heard a few glitches occasionally, still sorting things out, seems pretty stable though.
ORICO W6PH4 is working like a charm with A4 and AR. Bought it of Amazon Germany for 12,95 Euro yesterday.
pretty much the same as the one I got a little cheaper, gl3520 Chipset as suggested elsewhere seems to be good, and USB3 !
i have one of these and it works great, AK and AR, plus a Push, a keyboard and 2 SSD, no problem.
grin for overdub!
I use an Orico 7 Port USB 3.0.
ORICO A3H7 is its product number.
I think its somewhat flawed, because i get sometimes distortions from the A4.
I had my USB audio card connected to it as well.
I think the RYTM works better, i.e. does not drop out so much as the A4.
Enabled channels are 6 on A4 and 6 on RYTM.
I did now move the A4 directly to the computers USB 2.0 port, and will continue testing.
MB is Asus Sabertooth with Renseas NEC USB 3.0 chip.
You won’t find one any more compatible than this!
I’ve open up the ‘official’ Elektron Overhub and it contains two Genesys Logic “GL 3520” chips.
See my post here (at the end of page 3).
Well I couldn’t pass up $6.99 with free delivery on Sunday because my city has something like 5 Amazon warehouses pocked throughout.
GL3522 Chipset
Anyone know if this anker usb hub is MTT compatible? I couldn’t find any info on that aspect of it.
edit: emailed anker and will update my post.
Did you find one already? I’m curious 
No, I kept my cheapo belkin usb hub which has 1 elektron inserted, and the other elektron directly into my mac mini. This way overbridge works perfectly.
I borrowed this one from a friend:
http://www.belkin.com/us/p/P-F4U039/
It works on my Macbok Pro (early 2011) with RYTM and A4 attached to the hub.
Hi, guys!
I asked Anker about MTT-hubs they have and their answer is below:
"Thank you for contacting AnkerDirect and bringing your concern to our attention.
For your reference, you could take our Anker 4-Port USB 3.0 Ultra Slim Data Hub into consideration.
This is shitty hub, don’t buy it.
Overhub? Works for me
