What would be the best way to extract a useful USB debug trace for the kernel devs?
You need to get a usbmon trace. It would be nice to have a trace for working and non-working to compare. See <http://www.mjmwired.net/kernel/Documentation/usb/usbmon.txt> <http://groups.google.com/group/microdia/web/usbmon-user-guide> Graeme Gill.
