well, the flash key is working just fine (tried with mdk 10.1 cooker, kernel 
2.6.8.1-12mdk); i've rebooted my box and the behaviour was exactly the same, 
but after some minutes, it worked (more or less).
Details:
First insertion after reboot (tried also by changing usb port, no differences)

==================

Here i don't understand why i get this:
usb 5-3: new high speed USB device using ehci_hcd and address 4
and few lines below this:
usb 2-1: new full speed USB device using uhci_hcd and address 2
when I've inserted only one device :)

After this, I've removed an plugged again the key, with a different result:

===============

Note, no usb 2-1 related activity, and  I've been able to see this:

[root@kefk root]# find /sys -name diag
/sys/devices/pci0000:00/0000:00:1d.7/usb5/5-3/5-3:1.0/diag
find: /sys/devices/system/timer: No such file or directory

(/sys/devices/system/timer is a completely diffent story, it seems that timer 
is prepended with non-printable character)

I've tried several times to plug the flash key on a different system, no 
problems at all, and all usb ports of my box are working fine, tested with 
printer, scanner, bluetooth dongles, and so on..
