How to fix USB connectivity issues with DACs

It is important on a Windows computer to install the PS Audio driver before connecting the PS Audio DAC. During the install process you will be asked to connect the intended DAC for the PC to recognize. If this process has not been followed, it may be necessary to uninstall the USB driver and start over according to these instructions.

  1. Power off the DAC
  2. Unplug the USB cable from both ends.
  3. Restart the PC
  4. Uninstall the PS Audio USB driver from the “Program and Features” control panel
  5. Restart the PC
  6. Install the latest PS Audio USB drivers from the Downloads section (but don’t connect the USB cable until you are told to.)
  7. When the install process asks for you to plug in the USB cable, power up the DAC and plug the cable in on both ends.

The install should finish correctly.

  1. Hi
    I have a PWD II with firmware upgrade to 2.4.6

    I followed these steps to install the USB driver. worked smoothly on window 7 home version PC.

    But on window 8.1 PC, PWD II freezes and causes errors to
    other audio devices installed. Some are removed, some says malfunctions

    this happens if PWD II is connected to the PC during Window shut down and restart

    but if PWD II is detached from PC before Window shut down and before window restart,
    and then re-connect the PWD II to the PC during running Window would work

    this is a bother to me specially on my brand new PC running window 8.1 enterprise version on 5th generation i5 chipset, two SSD hard drives.

    I hope there is a quick fix from ps audio
