I was trying to get my M-audio Transit to work today. Basically it should be a standard USB audio device, but it needs to load a firmware first. For linux, there's madfuload available here: http://usb-midi-fw.sourceforge.net/ After modifying a few lines (taken from libusb), the firmware seemed to be downloaded correctly. It seems that you need to issue a reset so that the device gets recognized. libusb hasn't implemented this, so I tried un/reloading usb modules which seems to work. Any pointer on how to do this properly would be appreciated. In dmesg I get: uaudio0: <M-Audio Transit USB, class 0/0, rev 1.10/1.00, addr 2> on uhub2 uaudio0: ignored audio interface with 2 endpoints uaudio0: ignored audio interface with 2 endpoints uaudio0: ignored setting with type 8193 format uaudio0: ignored setting with type 8193 format uaudio0: audio rev 1.00 /dev/sndstat says pcm1: <USB Audio> on uaudio0 FreeBSD Audio Driver (newpcm: 32bit) Installed devices: pcm0: <Intel ICH4 (82801DB)> at io 0xe0100c00, 0xe0100800 irq 11 bufsz 16384 kld snd_ich (1p/1r/1v channels duplex) pcm1: <USB Audio> at ? kld snd_uaudio (1p/1r/1v channels duplex default) mode 1:(output) 2ch, 24/24bit, pcm, 48001-96000Hz mode 1:(input) 2ch, 24/24bit, pcm, 48001-96000Hz mode 2:(input) 2ch, 24/24bit, pcm, 8000-48000Hz mode 3:(input) 2ch, 16/16bit, pcm, 8000-48000Hz Something seems to be wrong, since I mostly hear noise as output (with faint artifacts of what it should sound like). I'm pretty much stuck here for now. This is on i386/CURRENT. More info can be provided if needed. Stefan
