I'm recently back to using Ubuntu, after terrible windows years, and I really like Ubuntu Studio. However, I'm having trouble putting my M-Audio Fast Track II to work. I see many people in forums complaining about similar problems with similar m-audio products, but I also see some folks say it works just fine.

About fast track pro, for instance, I've read it works 16 bit out-of-the-box, but to get it to record in 24 bits you have to compile the kernel. (http://joegiampaoli.blogspot.com.br/...ian-linux.html) I can playback audio with audacious through it, and I can hear my guitar on my amp (that's connected to the fast track's headphones output) Only if I switch direct monitor ON. I can't hear my guitar on rakarrack, audacity and ardour don't get any audio signal. Here's some command-line outputs to clarify:

 joao@joao-Satellite-L505D:~$ arecord -l && aplay -l

                      M-Audio Fast Track at usb-0000:00:12.0-3, full speed

Sorry my terminal is in portuguese, but I guess you get it. Dispositivo means device, the rest is similar to english words I wanted to get it running in 16 bit mode, at least, before I try to compile the kernel. Tried to force 16 bit in jack setup, didn't work.

It seems to be a problem with usb speed. M-Audio MKII has USB 2.0, but my lsusb output goes:

Bus 001 Device 007: ID 125f:c81a A-DATA Technology Co., Ltd. Flash drive
Bus 002 Device 002: ID 04f2:b128 Chicony Electronics Co., Ltd

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Does it mean that the fast track is connected and working as USB 1.1? How to get it to work as version 2.0? It doesn't matter in which port I plug it in, it's always Bus 003. My flash drive, however, as you can see connects to Bus 001. Please help me! Thanks
