That's a pretty bad scheduler if it can't schedule a single 12Mb device on a 480Mb hub. It's only sharing the hub with a USB keyboard. The audio being sent to it is less than 1Mb. > The -mm kernel series has a new, experimental scheduler in testing for > eventual mainline deployment that should allow all full-speed (USB > 1.1) devices to work with 2.0 hubs. I will look for this. Meanwhile I plugged my audio device into a USB port directly on the PC and it works fine. > > Monty > -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------------------------- Take Surveys.
