PG34WCDM - Unknown USB Device (Port Reset Failed)

Hi,

I was excited to receive a brand-new OLED monitor last week. Straight away I have set up the monitor with my PC over the weekend. All went well, and I have installed and updated all the drivers, including Windows updates.

However, I was surprised to see that Windows Computer Management had an error in one of the USB Controllers.

I checked the property of the USB Controller.

To make sure I even used different cables that I know that are working. I even plugged the monitor into my laptop with the same results.

Firmware Update executable didn't recognise the monitor I had to use the USB to put the firmware file and flash it from there. Even the ASUS Display Widget Center didn't manage to get the serial number.

It is every surprising and unfortunate to see this on a very beautiful and expensive monitor. I was expecting the best, though I shouldn't be.

Is there a way to have this fix? Is it drivers that needs to be installed or future updates that are to be release.

Hope to get resolution or I may have to DOA the monitor.

Kind regards,

Garry

Same exact thing happened to me.  I just received the monitor today with firmware 102 installed,  after upgrading to 103 I got the exact same error.  This kind of QC is not good when the Brand already commands an unjustifiable premium over competitors due to a perceived brand quality difference.  Bummer the state of ASUS in the last few years.

Hi @Gorio @robiatti ,

Thank you for your patience.we sincerely apologize for the delayed response due to the recent holiday, and we greatly appreciate your patience. 

To better assist you with your issue, we would like to confirm the following:

  1. Firmware version: Does the issue only occur on firmware version 103? If you have updated to a different firmware version, does the issue still persist?
  2. Factory reset: We recommend that you try resetting the display to its factory settings to see if the issue can be resolved.
  3. Cable testing: Please ensure that you are using the original display cable provided. If you have another cable, we recommend trying to replace it to rule out the possibility of a faulty cable.
  4. Different port testing: Please try connecting the display to a different display port on your computer to see if the issue persists.

Providing this information will help us locate the problem more quickly. Thank you.
