Our Trio 8500 is driving us mad. Every 4 minutes it is emitting a beep sound. After months of trying everything we could to get the beeping to stop, we finally figured out that the beeping is occurring because it is detecting a USB disconnect.
The Trio is connected to a PC in our conference room which is only used during meetings. When the computer goes to sleep, our PC seems to momentarily shut off the USB port. When this occurs, the polycom detects this and emits the beep sound. We figured this out by analyzing the diagnostic log:
0516102629|apps |4|00|USB Cable insertion detected 0516102629|apps |4|00|USB Cable insertion detected 0516103033|apps |4|00|USB Cable insertion detected 0516103034|apps |4|00|USB Cable insertion detected 0516103429|apps |4|00|USB Cable insertion detected 0516103429|apps |4|00|USB Cable insertion detected
Now that we know what is causing it, we have tried several things to stop this from occurring. 1st we updated the advanced Windows Power Options to disable the USB selective suspend setting. That did not work. Next, we tried to update the power management options for every USB device in the Device manager by Right clicking it, clicking properties, clicking the Power Management tab, then unchecking "Allow the computer to turn off this device to save power". Still beeps.
I'm at a loss. Is there a way to disable the USB insertion chime? If not, we need this bad! We have resorted to leaving the polycom usb disconnected when not in use. Crappy workaround.

Hello @polycomuser12 ,
welcome to the Poly Community.
Both the communities Must Read First and the FAQ reference the basic minimum information a new or follow up post should contain.
This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
As a reminder the basic information asked for:
UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.
Since UC Software 5.9.0 simply provide this via the Web Interface Diagnostics > Download Support Information Package
Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Poly to have an overview of the current software used. In addition, providing all details at the same time allow us to check logs or look up potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.
