Am trying to connect the new Palm M505 with its USB cradle and
  pilot-xfer. Perusing the net reveals that this might not yet work.
  What's the latest scoop?

  Meanwhile, I'm just trying to get serial USB working in my machine.
  I've gotten to this stage:

    [root@gbr:514]# cat /dev/usb/ttyUSB0
    cat: /dev/usb/ttyUSB0: No such device

  What would you suggest I do next? Here is some pertinent info. Let
  me know if I've missed something.

    [root@gbr:519]# l /dev/usb/ttyUSB0
