DT9812 not recognized by device manager on boot

[bsee]

I have 2 DT9812 that often fail to be recognized by device manager on PC reboot.  The error is "Device descriptor request failed".  This occurs on multiple computers running Windows 10.  The usbs are direct into the PC (no hub). Unplugging the device and plugging it back in fixes the issue.  Is this a known issue, or is there a recommended fix?

Installed drivers:

• QuickDaq 3.7.0.46
• DT Open Layers 7.8.2

Please update your system with the required software from the latest Omni CD.

This should update QuickDAQ to version 3.7.0.49 and install the most up-to-date drivers. If your DT9812-10 continues to have problems after doing this, I suspect an intermittent hardware issue.

I updated with the drivers you linked, but devices still are not always recognized on a PC reboot.  I've tested this on 3 PCs, and I have 2 DT9812 devices. The issue occurs with both devices.  Is there anything else i should try?

Hello @bsee.

Please reply with screenshots of the DT9812 device status and properties tabs in Windows Device Manager.

 

 

Also, does the module appear in the Open Layers Control Panel applet?  Please reply with a screenshot.

When I first rebooted, both device were not detected. At this point the OpenLayers entry does not exist. Image 1:

 

I unplugged and replugged both devices. Image 2:

Device properties.  For some reason I do not have the ability to update firmware from this page.

If you think a firmware update might fix the issue, how can I do this?  The option is missing from the device property status page.

Hello @bsee.

Thank you for the screen captures.  Unfortunately, neither of your DT9812 modules can be updated or fixed.  Since the serial numbers are over a year old, they cannot be replaced under warranty.  Sorry for the bad news.
