USB-6525 and USB-6000 Both will Not show up in Max at the same time

[RobSlad]

I am having issues with these 2 DAQ's working together on the same PC.  At first with my old LabVIEW 2011 SP1 PC the USB-6525's we working and everything was fine.  Then I Introduced a new USB-6000 to the Mix.  It was unrecognized by NI MAX.  I then read a few articles and decided to update that PC to the new DAQmx 19.1 which came with the CD for the USB-6000.  Now the USB-6000 is recognized and the 2 USB-6525's are not.  I have tried the FWUpdate.exe and no devices are recognized by it.  Any other suggestions to help bring my 6525's back online?

Thank You!

Update - My DAQmx Device Driver 19.1

Hi, May you please try disconnecting everything and updating daq driver through NI Package manger and then connecting back all HW one by one to the PC and check the result.
