Topic: Babyface loosing connection and causing kernal panics

i am using a Babyface with a Macbook Pro5,3 - 2.8ghz C2D w/ 8gigs of Ram. OSX 10.7.4

Yesterday while running audio from my babyface to a sound console, the babyface suddenly lost connection with the computer, and the level meters in Totalmix started flashing rapidly, as if it was connecting and disconnecting from the computer. I had the babyface plugged into one USB port, and a Dell external computer keyboard plugged into the other port. It was running off bus power. I was using Firmware v185, Driver v1.69, which I know is not the latest driver. Phantom power was not on, and no signal was coming into the device.

Today I downloaded the most recent driver, and using the same set-up, once again had the Babyface loose connection with the computer. This time it caused a system wide kernal panic, and I had to do a force restart of my computer.


Here are the console logs immediately proceeding today's kernal panic. They are similar to the ones yesterday when the Babyface lost connection.

Please help! I purchased this interface to have a clean and reliable interface for theater playback, but is useless to me if it won't maintain a reliable connection with my computer. I'm hoping someone can shed some light on this.



Thanks! Mark

Re: Babyface loosing connection and causing kernal panics

Can you please try with the aux power USB port as well, or a suitable external PSU attached?

Re: Babyface loosing connection and causing kernal panics

Thanks for your reply. I will try that when I have the chance to.

Do the console logs indicate that it was a power issue? I was under the impression that one USB port from a Unibody Macbook Pro could offer enough power to the Babyface. How much power does the Babyface need to operate properly? Do other's have any experience with powering the Babyface from one port of a MBP?

Normally, it's not necessary, but this might be a problem with your computer.

Re: Babyface loosing connection and causing kernal panics

I have not had an opportunity to test out the Babyface with an external power supply, or with the dual USB cable. I am working out of town, so it will have to wait until I return home.


In the meantime, does anyone know if there is a reliable utility or device I could use to test the output and functionality of my USB ports? I have been under the impression that only one port should power the Babyface properly, so because of this problem I'm having, I'm wondering whether there is something wrong with my computer as suggested by Jeff.


Thanks again.
