Can you explain what's going on in this little extract from Harald's syslog?

usb-storage: bus_reset called

usb-storage: usb_reset_device returns -19

It looks like the port's getting reset okay, but usb_reset_device() still returns an error code.

That's about what I see. It could be that the reset_device() logic is misbehaving ... after all, this particular device is getting handed from one controller to another.
