Instead, try connecting to USB ports at rear of the computer. However, be wary of USB ports on the front of some computer platforms that provide lower power. Normally, the internal USB Root Hub provides 500 mA of current per port. There could be a power consumption issue with the USB device.Update the USB device firmware, if applicable.If available, replace the USB device with the same device to further determine if this is a device issue.Check the Audio Device Properties of the Sound Settings on the computer to ensure that the USB device is properly detected and configured as the default device for recording.If the audio record channel is not working on the computer, the issue is not with Dragon Medical and should be addressed by the customer's computer support staff (IT/IS department). Click the red record button on the Windows Sound Recorder interface to record, as the record button on the USB device will not be active. If the problem continues, test the audio record function of the USB device with a third-party application like Windows Sound Recorder.If the USB device is connected to a USB hub or a laptop docking station, instead unplug and connect the USB device directly to a USB port on the desktop computer or laptop.Next, try rebooting the computer with the device connected.Close and re-launch the effected application(s) and try to reproduce the issue using the same steps.Start troubleshooting by capturing the exact wording of any error messages, if presented.There are several troubleshooting steps below when USB device enumeration fails. Further, under certain circumstances when switching USB ports, re-enumeration can fail, resulting in Dragon Medical being unable to either recognize, or use all of the function of, the PowerMic II.

This is a function of the Windows operating system, and not Dragon Medical. This means, for example, that when a PowerMic II microphone that was successfully used on one (1) USB port is unplugged and then plugged into another USB port, re-enumeration must take place. The detection process for USB devices by Windows operating systems is called enumeration and involves multiple steps through the operating system software stack, USB hub driver, and PnP Manager.Įach time a USB device is plugged into a USB port, enumeration must occur, even for devices previously enumerated on that computer. Depending on several factors including the actual USB device, computer hardware, operating system, and user's workflow failure to detect USB devices can occur. Detection of these devices by Dragon Medical is contingent upon a Microsoft Windows operating system successfully detecting the same USB device, first. Dragon Medical supports USB input devices (microphone and headset).
