V-4EX: Troubleshooting USB Video and Audio Output
Troubleshooting Video
Try a different USB port on the same computer.
Try a different USB cable, preferably one between 3 to 10 feet long.
If using a USB-C adapter:
Unplug the adapter from the computer and the USB cable from the adapter. Then, plug the adapter back in, followed by the USB cable.
If the adapter is a breakout cable to multiple connectors, disconnect any other video devices or bus-powered hard drives.
Try a different one if possible.
If you experience record issues using our free VR Capture software, please try recording to your system drive.
If you record to external media, like a USB flash drive, format the drive between recordings
Try the following:
Shut down your computer.
Unplug other USB devices.
Note: Most computers can only support a single USB video device. Disconnect any USB cameras before connecting the V-4EX.
Connect the V-4EX directly to a USB port.
Note: Bypass any hubs or extenders.
Turn on your computer, and open your streaming/recording software/website.
Check the USB Status again in the menu.
If using a Mac with Screen Sharing enabled, temporarily disable it and test again
If using a Mac with a newer OS and a high resolution desktop (like a Retina display), you can try opening VR Capture or your streaming and recording software in low resolution mode:
Close VR Capture (or alternative software).
Go to Finder , followed by Applications .
Right-click on VR Capture (or alternative software), and select Get Info .
Check the box for "Open in Low Resolution" .
Reopen the software, and test again.
More information available in this article .
If the above suggestions do not resolve the issue, try a different computer.
