Reading through that doc it appears that the device operates in a USB standard mode and PSA2 mode ( a MS Windows mode). Maybe when it is resuming it is resuming to MS Windows mode instead of the USB standard mode, or the other way around. There is a command for getting the mode back: 0x80: Report Current PSA2 Mode State When you plug it under Ubuntu the buttons for volume and mute work and generate UI on the desktop. It looks like the thing needs to be in PSA2 Mode for those controls to work. Could it be that the device is not reporting the resume event up the stack to wherever this control software is, and the control software is confused about what state it in? -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------------------------- Using Tomcat but need to do more?
