I just played around with my Sonica a little more (on i386) and found that after the firmware upload was attempted, madfuload was unable to reset the device. It looks like the device auto-reset, as the USB device changed (increment by one). The usb IDs have also changed. Here's a nice big log. ----- lsusb -v (before) Bus 001 Device 010: ID 0763:2805 Midiman Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 254 Application Specific Interface
