Connecting via Powered USB Hub - Windows 8 BSOD Crashes

Hi all,

 

I'm having issues with the Ultranova connecting to my Windows 8 computer via a USB HUB (http://www.hootoo.com/hootoo-ht-uh002-usb-3-0-4-port-hub-with-usb-cable-...). It crashes (BSOD) EVERY SINGLE TIME. I've tried uninstall/reinstall the Novation USB driver (ver. 2.3) as well as the Ultranova software but it doesn't seems to help. Does anyone have any suggestions on what I might need to do?

 

Thanks,

Kenny.

Have you switched the power switch of the UN to the right position for USB powered?

I have always used the "ext" DC (powered source) instead USB powered.

Thanks.

1. Have you tried plugging it directly into your computers USB port without the hub?

2. BSOD usually driver or hardware related, so to rule out drivers you could try a system restore to a point before you installed any nova drivers possibly?  Or was it quite a long time back now?

3. What is listed on the BSOD?  Any drivers etc which will give a clue?

Could you also explain how it crashes? is it when you switch the nova on when at the desktop?

Or when you're in your music software?

i.e. any other factors?

Plugging the UN directly to the computer USB port works fine. I was thinking there are some issues with the USB drivers but I'm not sure which (UN or the USB Hub.) I have a Focusrite Saffire USB audio/midi interface and a Behringer UCA202, and they works with the USB Hub just fine, therefore I'm wonder if it's UN driver issue. I'm able to reproduce the BSOD every single time by doing this:

1. Connect the UN to the USB Hub.

2. Open any DAW -> BSOD crashes, or

3. Open the Audio/Sound (by right-click on the speaker icon) and select "Record". Open the "Playback" doesn't give the BSOD.

Hmm, that's 3 audio devices attached to the same hub then.

Does it run ok from the hub if you remove the Saffire and UCA202?  

If i had to guess this could be your issue:- There's only so much data that can travel from the hub to your computer so wonder if you're pushing the capabilities of that usb port? You've basically got (If your sapphire is 2/2) 12 channels of audio going through that one connection (3x stereo outs/ 3x stereo ins).

Even though the usb standards allow for quite a bit of data (I beleive 10 in/10 out is the theoritical limit), the ports on your pc are running on shared resources so limited in that respect and maybe throwing it out.

This is only guess work of course, but would be interesting to see what happens if you plug that in on its own through the hub.

You using USB ports on the back of your pc i presume? The ones on the front have less power, so if you're using that for your hub, try using the ones on the back.

I didn't mean that I have all 3 audio devices connected at the same time, that would be crazy :D What I was saying is that the Saffire and the UCA work (independently) just fine without any issue when connecting to the Hub, while the UN does.

Thanks.

lol hey, we all have our secret fetishes - thought yours was USB Audio! ;)

Sorry mate, just to clarify - Does UN still cause problems when connected to the usb hub WITHOUT anything else connected?

Also, on the BSOD, what driver is listed - Is it Usbhub.sys by any chance?

Yep, it's something around nvusbhub or something similar :) Anyway, for now I'm just going to connect it directly to my computer to avoid these kind of issues.

There are some other issues that I've just found out last night on a gig though :) Hopefully it's a user issue! See my other post on Transpose while using MIDI OUT port (no USB).
