USB hub (latency?)

Hey guys, just wondering if anyone currently uses a USB hub during their gigs. I’ve had my eye on this one, as I’m going to have a few controllers (eek), external hard drive and just want some room for other stuff if necessary.

Was just wondering if there were any Do’s or Don’t when looking to purchase these. Much thanks in advance!

I use a D-Link powered hub. Just try to get a hub with it’s own external power source. Some devices such as HDD and USB Mixers like a lotta juice. I couldn’t tell if it had a power supply, but I did like that top load.

The main issue with latency from a USB hub is how many translators it has, without getting too technical some USB hubs have one translator for all 4 ports, this is what will introduce latency to your system.

Good usb hubs will have one translator per port, these hubs offer the best performance.

Unfortunatley most places wont let you pull apart a product to check which chipset is uses before buying i.

awesome, thanks for the response guys!

Maybe people here (Including me) can make a list of the “good” hubs for reference before buying stuff :slight_smile:

thanks, nemo! thoughts on this one?: Amazon.com

We would certainly like to hear which are the good ones !

just to bring up this thread again,
does anyone have a suggestion for a nice, fast, powered USB hub??? Cheers!

Hi guys,

I’m using this logitech hub: Logitech United States

with an external adapter for gigs or not when at home.

I can’t feel any latency at all, it really works good for me.
Very nicely build (solid and compact, with case =) )

And i don’t work for them haha

Fatlimey mentioned another good one in a thread but i cant seem to find it - if anyone can find it ill put it in the FAQ

This is the one - a multi TT hub.

Just the information I needed thanks for the reccommendations :slight_smile:

I’d Just like to say that I recently returned the Macally TRIHUB7 USB port because it doesn’t work with the Vestax VCI-100SE and it certainly doesn’t work with any USB soundcard.

14

just ordered the same one. Called my friend who is working at logitech to ask about the converter. He told me there was one converter per usb slot.

Swiss quality! YAY!

Thanks for mentioning that - this was the one I was thinking about getting. What did you end up going with?

16

Just did a little research. Here’s a great article explaining the design and performance differences of both a single tt and a multi tt hub. They also ran benchmarks. What really sucks is both of my hubs use the same stupid single tt gl850a chipsets. (just opened and checked) And I’m sure that’s why i sometimes have problems w/ my vci (w/ ac adapter) and audio 8 on the same hub. I guess I’m going shopping.

Trying to do some research to see if it’s single or multiple TT, but I’ve been using this one for a while now. http://catalog.belkin.com/IWCatProductPage.process?Product_Id=377068

I like it because it’s 7-port but has the detachable section that is a portable non-powered 4 port hub which is great if I’m using/programming just my controllers I can just grab it off and take it with me. While the base is powered the 4-port portable hub is not, but can still power my 3 Nanos and my PadKontrol with no problem at all and no latency that I can feel.

Well true tuna, I just ripped open the 3rd usb hub I’ve owned. The third I own is a Belkin, slightly different looking version of yours, and it’s chipset is a GL850G. Still a single TT chip. So, here’s the stackup of hubs i own: Macally 4port i own Uses a Genesys Logic GL850A as well as my Vantec 4port. The
Belkin uses a different revision (hence the G) of the chipset but still very similar design. I assume the differences are a smaller manufacturing process. I am assuming this is a popular chipset for manufactures.

Came across an insightful thread on this (follow the links to the related threads as well):

http://episteme.arstechnica.com/eve/forums/a/tpc/f/24609792/m/802007017831

From that, it suggests that there is only one Belkin Multi-TT Hub, the TetraHub 4-Port. The 7-Port version of that even doesn’t sound confirmed.

I think we are up to 3 confirmed Multi-TT hubs now?
