No manager would insist that you write a driver for a device that does not require one. He would be fired for wasting company money on its development, and for creating a product that is of worse quality than the competition. USBAUDIO.SYS is 8 years old. It has been through numerous revisions and bug fixes. It is well-tested, robust, and reliable. You could not possibly hope to write a better replacement on your own. -- - Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
