Kernel: 2.6.9-1.1009_FC4 (Fedora Core)
I get a kernel oops when my M-Audio Sonica disconnects after firmware
load. Once I reboot the device works. The firmware is loaded with madfu:

usb 3-2: new full speed USB device using address 3
usb 3-2: reset full speed USB device using address 3
usb 3-2: device firmware changed
