Toshiba 80GB USB Storage Device

[das]

I cannot access a Toshiba 80GB USB Storage Device with Feisty. 

'dmesg' is reporting it, but 'lsusb' is hanging the command prompt, it
is not returning anymore, I have to just close the terminal window.

I am quoting here the relevant portion of 'demsg' output, after I
plugged it:
