+ The option is needed for devices that have multiple streams
+ defined in multiple USB interfaces. The driver may invoke
+ registrations multiple times (once per interface) and this may
+ lead to the insufficient device enumeration.
+ This option receives an array of strings, and you can pass
+ ID:INTERFACE like ``0123abcd:4`` for performing the delayed
+ registration to the given device. In this example, when a USB
+ device 0123:abcd is probed, the driver waits the registration
+ until the USB interface 4 gets probed.
+ The driver prints a message like "Found post-registration device

+ notice the need.
