This article helps to fix an issue in which Windows 10 doesn't install specific drivers for USB audio devices on the first connection.
Bring up drivers. USB Function driver bring-up is only required if you support USB Function mode. If you previously implemented a USB Function driver for a USB micro-B connector, describe the appropriate connectors as USB Type-C in the ACPI tables for the USB Function driver to continue working. We are having a problem with the Polycom CX300. When we plug the device to the computer, it is recognize and the process of installing the apropiate drivers starts. The result of this process is shown in the attachment. Basically is that the driver cannot be installed and therefore the phone doesnt work.

When you connect a USB audio device to a Windows 10 Version 1703-based computer the first time, the operating system detects the device but loads the standard USB audio 2.0 driver (usbaudio2.sys) instead of the specific device driver.
This issue occurs because the USB audio 2.0 driver (usbaudio2.sys) isn't classified as a generic driver in Windows 10 Version 1703. Therefore, the system assumes that a compatible, nongeneric driver is installed for the device even though the driver is generic.
This issue also causes Windows 10 Version 1703 to postpone the search for other compatible drivers through Windows Update that typically occurs immediately after you install a new device.
To fix this issue, use one of the following methods.
To resolve this issue, install update 4022716.
If the device-specific driver is distributed through Windows Update, you can manually update the driver by using Device Manager. For more information about how to do this, see update drivers in Windows 10.
If the device is not yet connected, first install the device-specific driver, such as by using the appropriate installer. After the device-specific driver is installed, Windows 10 will select that driver instead of the standard USB audio 2.0 driver when you first connect the device.
