      Well, my next step will be to power the usb device via a 5 volt line directly taken from the power socket. This need a hacked usb cable, which I have.

      The next next step will be to monitor the serial line for kernel messages.
      Can someone confirm to me that the kernel log messages are sent on the internal uart available via the 4-pin header?

      Sebastien.

      PS: have a look at what happens when I plug my smart card reader:
