The device seems to disconnect when you try to read
the firmware.  I get this when I try:

[root@ps3-nfs ~]# dfutool archive ps3.dfu
Available devices with DFU support:

         1) Bus 002 Device 003: ID 054c:0267 Interface 3

Select device (abort with 0): 1

Can't identify device with DFU mode

And see this in the log:

May  8 15:50:07 ps3-nfs kernel: usb 2-2: reset high speed USB device using ps3-ehci-driver and address 3
May  8 15:50:07 ps3-nfs kernel: usb 2-2: USB disconnect, address 3

Any suggestions?
