US-144 MKII with Yosemite MacOS

[Sunith Balan]

All,

Did anyone try US-144MKII with the latest Yosemite?
I did try and it works partially. When connected the input and output works for few minutes before which the signal stops.

Are there any new updates coming for US-144 MKII on Yosemite to fix this issue?

Working fine here, play & record for over an hour. 10.10 on 2011 Mac Mini.

Hey Redbus,

I am using the 3.00d14 beta driver that you had sent earlier for Mavericks.
I used it for more than an hour. Mostly playing and recording through garage band. When I start, there are no problems. After few mins of recording/playing, signal stops. Then i go to preferences and then select the input/output to built-in and then change back to US-144. Then again it works for sometime.
This is on 2010 13inch macbook pro running Yosemite.

Open the console log (under Applications/Utilities), and see if there are any system level errors occurring that coincide with when the audio drops out.

I think these are the errors which occur:-

I don't think this is a driver problem. Do you have an aftermarket SSD or other upgrade in that machine?
Could it be as simple as your hard drive being worn out and slow?

 

[Sunith Balan]

Redbus,
No SSD or other upgrade..
But the problem started exactly after Yosemite upgrade. Had the issue been hard drive being slow, then the problem shld have come before with Mavericks as well

 

[Sunith Balan]

Guys.. Anyone else have the same problem?? I am not able to use my TASCAM since Yosemite upgrade :-(

 

[Sunith Balan]

I am still getting errors and not able to use US-144 MKII on yosemite.
Help pls

Red Bus,
could send me a driver that works with my US-144MKii? My system is OSX Yosemite. My email is srso@hotmail.com
thanks

 

[Sérgio]

Red Bus, installed the driver. I can send signal to the computer, a microphone or guitar. However, it seems that the board does not receive sounds via USB. For example, if I use a VST, I can not hear anything. What could be happening?

 

[Sérgio]

I add that on the same computer have another partition with snow leopard, where my US144Mkii works fine. So, I do not know why in Yosemite the output no works.
