Superspeed USB 3.0 dock not compatible with Zenbook Prime UX31A-DH71 - WIN 8 tested???

Superspeed USB 3.0 dock not compatible with Zenbook Prime UX31A-DH71.

I downloaded the updated WIN8 driver and installed successfully. Then powered up and connected your device.

When I plug in your device I have USB controller error.

“Windows has stopped this device because it has reported problems (code 43)
The USB hub failed to reset”

I have attempted the device installation twice with the same result. The device rendered both USB3 ports useless. The USB needed to be reset via device manager.

Very disappointed.

Hi Marc,

Sorry for the frustration! Yes, there’s a problem we’ve been trying to track down with Windows 8’s USB stack and the firmware on the UD-3000, and it manifests in a particularly bad way with certain Intel Ivy Bridge host controllers.

We’ve had a “Not currently compatible with Windows 8 on USB 3 Intel host controllers.” warning on the Amazon listing (…) because of some early cases we hit. We need to strengthen that working.

There are three options right now for fixing the issue. We’ll help with any / all of these, until we have you up and running:

  1. Installing the Intel USB 3.0 stack resolves the issue. Instructions posted here:…

  2. An update to the UD-3000’s firmware solves the issue. Unfortunately, if you have this Win8 “code 43 on the xchi root hub” issue, you may need access to a Windows 7 USB 3.0 to do the update. Just plug in the UD-3000 and run this utility to update the firmware:…

The code 43 problem will then be resolved in Windows 8.

  1. We know the first 2 options aren’t for everyone. Email your Amazon order # to with a title of UD-3000 firmware update, and we’ll get you a pre-tested replacement unit with updated firmware, along with a prepaid return label for the old UD-3000. Marc - you’ve already emailed us, we’ll work with you directly there.

Again, my apologies for the frustration while things stabilize after the Windows 8 launch. If anything doesn’t work, please contact us - we’ll be able to make things right via one of the various options.



Thanks for your quick response. I have forwarded a ‘private’ email to you.

I look forward to prompt resolution of this issue.


My UD-3900 does the exact same thing. Was this ever resolved? If so how? Mine use to work fine then I moved desks one day and reset everything up and now it does exactly what Marc stated above.
