Hi, I'm currently trying to get a M-Audio Fast Track Ultra 8R working. The device has the USB-ID 0763:2081. I applied the patch from Clemens Ladisch[1], written for the "Fast Track Ultra" (w/o 8R), but changed the USB ID to match the "8R". Now the device is essentially working, i.e. I'm getting 8 input and 8 output channels in Jack. What's missing is access to the DSP mixer and effects. Is there any way I can help anybody helping me in getting these features into the driver? On another note, I'm not sure if I can get the device to work at 44100 Hz. Can anybody enlighten me, if it's possible? See below the relevant part of lsusb -v. Thanks in advance, Felix [1] http://www.mail-archive.com/alsa-user@xxxxxxxxxxxxxxxxxxxxx/msg25385.html Bus 001 Device 010: ID 0763:2081 Midiman M-Audio RunTime DFU Device Descriptor: bLength 18
