USB Ports not working

Hi, all of my USB ports are not working on my device. The DVI and HDMI ports are working fine, and I have tried to reset the device by unplugging it from my computer, then unplugging the stations power. I then replugged the power back to the device and then plugged back to my computer. Resetting in this way still has not activated the USB ports.

Is there software that I need to install to get those working or something? Please help.


Thanks for posting!

This will create a ZIP file on your Desktop containing system logs and information. Please send this ZIP file to us directly at with the subject line: “Ticket 278903”

Additionally, please include the Amazon Order ID associated with your UD-3900 in the email.
