The AT2 is a mass storage class device, so it should use the standard USB class drivers included with the Windows operating system. Cypress also offers a driver for Windows and another for Mac OS X. These drivers can be used in place of the native drivers if there are problems. Win98SE does not have a USB mass storage class driver and requires the Cypress Windows Mass Storage drivers.
The Cypress drivers are located at: Mac OS X Mass Storage Driver( http://www.cypress.com/?rID=14396 )
Windows Mass Storage Driver ( http://www.cypress.com/?rID=14453 ) It is recommended to use the standard mass storage class drivers, when available in the OS.
