Promethean 300 boards and usb audio
Our new promethean 300 boards keep loosing their usb audio connection each time the laptops they are connected to shutdown or restart.
The only way to get the audio working again is to pull out the boards USB connection and plug it back in.
I have update the promethean drivers( v 18.104.22.168)and active inspire software to the latest. I have checked the usb settings for the laptops in their BIOS
and nothing seems out of order. The laptops are Dell latitude E5520 laptops with Windows 7 installed.
I have even set the Promethean USB Audio as the defualt audio device on the laptops but each time a laptop shuts down or restarts you would need to re-plug
the usb connection for the audio to work even though the boards reconnect after the shutdown or restart.
Has any one encountered this problem and is there a work arround?
