When using the Trio 8800 via USB for audio only on both a Surface Pro 4 and Lenovo Laptop running Windows 10 Enterprise 64bit O/S I am getting "Unknown USB device (Device Descriptor Request Failed)" within Device manager. Anyone else experienced this or managed to resolve?

Hello DanKennoyModality,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
