USB interface stopped working after update

Back to an unresolved issue I posted sometime ago. I did some more tests this week and found out the following (I did this test twice and obtained the same results in two different machines):

1) I install Ubuntu Studio 12.04 from scratch;
2) I try it with my PreSonus AudioBox 1818VSL USB interface. Open Jack, Jack sees interface, Start Jack, Start Hydrogen, Play a Demo, it all works and I get sound out. Happy!
3) I then turn off the computer and the interface. Then turn them back on;
4) I repeat the steps of #2: open jack, jack sees interface OK, I start jack, I start Hydrogen, open a Demo, and... no more sound comes out of the interface. I don't even see the meter lights anymore. Still, Jack recognizes it and starts correctly. But no sound anymore.

With this, I rephrase my original question. The problem was not a recent software update, as I had thought: now even with a clean, fresh install of Ubuntu Studio, the interface works the first time, and after rebooting the computer, it never works again.

I've tested the audio interface on a Mac computer and it is working (in fact I bought this PreSonus recently, it's brand new). If I boot Ubuntu studio from a live CD, the interface works again.

Any ideas on how to solve this mystery?

Thank you very much for any help,

I didn't use synaptic, but I copy below the contents of history.log from /var/log/apt/ 
The interface was working fine until 2012-09-24. After those updates it stopped working.
Thanks for any help,

       5. Re: USB interface stopped working after update (Ralf Mardorf)


    I have Ubuntu studio 12.04 installed on one laptop, and regular Ubuntu on another (also 12.04). Until a few days ago, both systems used to work fine with a PreSonus AudioBox 1818VSL USB interface. All of a sudden, the two laptops are no longer working with this interface. My only guess is that this was caused by some kind of software update (I usually do all required & recommended updates suggested by Ubuntu).

    To be more precise, Jack still sees the USB interface as before; I am able to start jack with the PreSonus, I see all the ins and outs in the connection window. But no sound seems to arrive in the hardware. No sound comes out. I used to see the AudioBox meters lighting up last week; they no longer light up this week. I've tested the audio interface on a Mac computer and it is working. In fact, if I boot Ubuntu studio from a live CD (that is, without any recent updates), the interface works again.

    Has anything like this happened to other people this week? Any tips on how to solve the problem?

    Thank you very much,
