UX2 (driver?) problem on win7-64bit
by leavit on 2011-08-13 10:51:15.5470


I have been using line 6 recording gear smoothly for years now. But when i upgraded to win7 from Xp my Ux2 have been ragequiting on me randomly.

Ive googled this and found similar problems for other UX2 users. I also found i have no usbfilters. And I have updated the drivers. I also use big buffer sizes as often i can. I may add that i use the ux2 all the time while am at the computer, not only when i'm recording.


The Ux2 stops working randomly with no output signals and no inputs working. But the 'retro db meters still glowing.

After this have happend i sometimes get a bluescreen. Sometimes i get to finnish what ive started and begin to restart the computer. But when i reach the Windows 'Shutting Down' screen it never does shut down, So i have to force it off.

And if i'm not getting a blue screen and have the force the computer off. Every application running seems to be affected by it somehow. They stop responding.

What could be the problem? Can i fix this myself?

Its getting frustrating.

Hey man!

Got almost the same problems. It seems that Line6 can't come up with a decent driver.

I think the problem is on their side and not ours. Maybe some day they are going to get their asses and fix a new driver that works well.

I'm not going to jump to conclutions just yet.

Because its to scary for me to concider you are correct.

i'm using this device frequently in live situations.

Ive encountered line6 support b4 and they did a great job.

  BSODs are often related to drivers on a computer system conflicting with each other.


  Be sure your video card drivers are up to date as this is often related to the issue.


  Also, you can use this link to try and diagnose which driver is causing the issue on your system:


  As far as the dropouts are concerned, have you tried the optimizations in our USB troubleshooting guide?

This often yields interesting results from discussions from users who have been experiencing similar problems.


I'm going to start by uninstalling my microsoft Intellipoint driver for my mouse just incase they are conflicting. and my lexicon lambda driver and a western digital external hdd usb driver. Even tho i had these same drivers along with the ux2 one while i was running xp32bit.

And yes i have all the latest *smoothest* drivers for my computer.

I also want to argue that i'm not looking to optimize my pc for recording. If my computer had kept chrashing during big and recource consuming recording sessions i wouldnt have come here. I would buy a new cpu and some more ram -.-

It normally chrashes while i'm on facebook or watching Battlestar Galactica. It has chrashed during a recording session once maby, but i can be sure that it was a coincident. this has not to do with cpu or ram overloads.

Hey man!

If you got a Logitech Webcam or other, try unplug it and see. I did, haven't got any sound problems for 2 days now.

I have the Logitech Pro 4000 cam and use Vista 64bit driver for my Win7 64bit without the added software - it works fine.

Is there any chance that my built in soundcards driver is fucking with the ux2 one? It sounds stupit but..

Re: RE: UX2 (driver?) problem on win7-64bit

I always disable my motherboards integrated sound card before I use any other sound cards.

Try unplug the webcam or unsintall the drivers for it and see if it works better.

Just a cheap shot man. It worked for me and I tried all the so called "solutions".
