Hi:
I set up my USB 2-channel audio interface (Event EZbus) this
weekend. Amazingly, when I plugged it in, up comes this panel asking me
if I wanted to configure it! I didn't expect to get even this much for
something that had no driver! After a day of working with it, it came
down to 2 choices:
1) I could have my usb audio interface working, but not at the
same time as jack or any jack dependent programs that I had set up (such
as zynaddsubfx, muse). Also, jack gives 'pcm' errors and then shuts
down.
2) modify my /etc/modules.conf file to allow jack programs to
work, and also my USB audio interface (but no tracking /dev/dsp
device), but with awful cracking upon playback.
I think I am having 'pcm' troubles, but am not sure. I am still
trying to learning all of the modprobe commands. But I could really use
some help on this. I feel like I am so close to kissing Macs goodbye if
I can just get this to work. Below is my /etc/modules.conf file (I
commented out any oss and rmmod-ed them). If I choose option 1 above I
still get insmod errors at bootup, but all still works, except for jack
as mentioned.
I guess I should mention that there is currently a SBLive! card
installed in a PCI slot also, but I am trying to bypass it and use only
my USB device, even though I left it in its PCI slot on the motherboard.

I would really be grateful for any help someone could give,
