Is there a way to set the kernel to not unregister a USB mass storage
device if the partition table is unrecognized?

I have a Xbox 360 HD connected to a generic SATA-USB bridge, but the
proprietary partition table means that the
device unregisters before I have a chance to intercept in, e.g. virtualbox.

Where, in the usb code, need I comment a few lines to disable this behavior?
