You can just return a pointer to a "valid" object if you want to keep
the usb subsystem from reporting that "No driver was found for this
device". Then when the device re-enumerates itself, disconnect will be
called in your driver, then the new device will show up.
I've tried this for one of the usb-serial drivers in the past, and it
worked just fine (don't think I ever pushed the patch into the kernel
though, as it didn't seem like a necessary thing at the time.)
Hope this helps,
