I happen to have an issue with some USB DAQs.
I have 3 USB-1024LS DAQ connected to the same PC, and those are being used trough the software TestStand with the help of a .NET class.
The problem resides in the fact that each time I try to send a port configuration command to one of those, the other DAQs return to a default configuration.
As an example, let's say I configure all ports of one DAQ to work as Outputs, as soon as I try to configure the second DAQ, no matter the port type configuration, the first one returns to its initial configuration which happens to be all ports as Inputs
