You were my best hope, cause i did something similar for
a Hp 720c on parallel port, and it worked. I did excatly
what you've just said.
But the whole thing still doesn't work properly.

I finally could mount the device, then read the first root directory.
But couldn't get more... always got what you see at the end of the
error message.. I/O error, which resulted in no files appearing from
a 'ls' command.

I've got those kind of message now :
