Ok, it seems that now the device is detected without problems at first try; 
I've tried several times with this setup in modprobe.conf:
options usbcore old_scheme_first=1
and I'm unable to reproduce the behaviour of missed detection of usb device, 
no matter how many times I can try, so I think you have hit the point, many 
thanks :)

As expected, the faulty behaviour of kobject is still here (double 
registration..), but now the device is working on first try, so half the 
problem is gone away :)
I get some scsi errors about unit not ready, but the driver seems to handle 
this quite well.
If this can be a useful information, on this box are present 5 different 
scsi-like devices: cdrom,cdwriter and scanner attached to aic7xxx controller, 
SATA disk on ich5/abit ic-7g builtin controller and flash usb key. So far the 
only strange behaviour is with usb flash key.

Below you can find as usual the full syslog report..

Many thanks for your help.
