Aparently I need USBOOT 6.5 to format the pendrive that has the problem.
The message is the same on other computers (Also XP)

Where did the USBOOT idea come from? From what I can translate that is an old floppy drive utility.

XP should have no need of USB drivers or tools. Are you sure that the Pen is working?

Does it power on? Is it detected once attached? Is it new? Ever been used? Do you have another you can try?
