--- Comment #10 from Alan Stern (stern@rowland.harvard.edu) ---
The attachments are pretty clear. The most likely explanation is that
something gets sent to the device under one kernel but not the other, something
which causes it to change its firmware.
The next step is to collect a usbmon trace showing what happens when the device
is plugged in. As root, do:
cat /sys/kernel/debug/usb/usbmon/1u >FILENAME
before plugging in the device. A few seconds after the Xone is plugged in,
kill the command with ^C and attach the output file to this bug report. Do
this for both of the kernels, and we'll see if anything is different between
them.
