or, imho better way, - when completing init of usb bus, first scans it and connect all devices and only after all devices were connected returns to main kernel code.
That might not entirely solve the problem, since the relevant device could drop off the bus temporarily, but it seems like it'd be a step forward. How would you make root hub ("bus") initialization do that?
i'm not familiar with linux usb implementation so may be it's wrong:
after sending global reset over the bus you can manually check (not trough the hub driver) root port connection status and call enumeration if needed.
another way- add an option to kernel for booting from usb mass-storage, where place an input-waiting code, because my current solution adds such delay for all boots (ide,scsi,usb)
