I have 2 NI5132 USB digitizers. Either one alone works fine. But if I plug both into the USB bus, then the last one connected produces the error message "Error BFFA666A NI Platform Services: No transfer is in progress because the transfer was aborted by the client....." with a status code of -50405. This error occurs when the niScope_InitiateAcquisition function is called for the offending scope. Up to that point, all the needed niScope_ function calls work, namely:
Init, ConfigureVertical, ConfigureHorizontalTiming, ConfigureTriggerImmediate, ActualRecordLength

Hello PhilLC,
According to this KnowledgeBase, the issue you are experiencing is a common incident that arises when using multiple USB devices, and it is a system dependant issue. Fortunately, resetting the device should do the trick for reestablishing communication. Please reference Issue 2 in the KB for the steps to resolve the error.
