Hi,
I believe there is a race condition for userland in hcd.c where the
kernel sends a uevent before the underlying sysfs is fully populated:
(drivers/usb/core/hcd.c)
/* starting here, usbcore will pay attention to this root hub */
retval = register_root_hub(hcd);
if
on the usb_bus_notify dispatcher.
