This driver is ONLY for PNY's Attaché 64MB pen (per site's info). This seems to be USB 1.1 from what I've read. XP does not need this driver to work, but Win 98 does. It is advised that you install the driver within the self extracting exe before plugging in the pen drive to 98 and 98 SE machines.
The following files are found inside the driver download file.
