A full-speed isochronous device uses a larger percentage of a full-speed controller's available bandwidth than a high-speed device uses of a high-speed controller, but having a full-speed device on a high-speed controller doesn't have any more impact than a high-speed device of the same rate. Further, it's quite possible to have a USB Audio 1.0 device run at high speed, as long as your isochronous interval is not smaller than 1 per frame. -- 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.com/
