the bold part is new, never reached this part, so now no more connection problem, the only problem is device not found
this make me feel better, a problem solved, 1 more problem left

Looks like your mining software and network connections are running now, but there is no connection to the blades
"Fri Mar 28 22:48:02 2014 kern.info kernel: [   43.960000] bitmain 1-1.1:1.0: USB Bitmain asic #0 now disconnected"

What does it show at the lower part of your Status, Miner status screen?  Do you see something like

Chain#   ASIC#   Frequency   Fan   Temp
1        32      350
2       32      350

If not, then this is another potential sign that your blades are not 'seen' by the controller.

Perhaps there is a wiring/connection problem between the controller board and the blades - Turn the system off, disconnect from power - check that the cables between the controller and the blades are ok.  You could unplug the multi-wire connectors one at a time and inspect the contacts to make sure that none is pushed back inside the shell, then reconnect.  Another thing that you could try is to disconnect power to one blade at a time and run it with just one blade.
My impression is that all S1's are tested in the factory before shipping, so the problem occurred later or external to the Antminer itself.  What sort of power supply are you using?  Is each blade connected to a separate 12V rail or are you using a 'daisy chained' single rail with 2 PCI-e 6 pin connectors (the latter may not work, as a single rail might go into over-current protection).

Good luck
