Hi Fausto, I just received another USB-2404-UI and tested the fix you postet. It works😊 (both in development environment as well as in an exe)!! Great and thanks for such a fast fix. Herby

Hi Fausto, this is really great! What a service!!! Now, the USB-2404 is at the moment at the partner company to figure out, how to mount it in the final instrument. I will thus have to wait a few days, until I can test the fix (next week, maybe Wednesday or Thursday). I will then immediately check the fix and report the result. Thanks!

Thank you a lot, Fausto!!!! Herby

Trying to acquire data with the newly received USB-2402-UI using LabVIEW 2020 64bit, the VI "Stop Task.vi" regularly crashes LabVIEW. I observed this using the simple code below: As I do not observe these crashes when using the same code with a USB-1608GX device using 64bit and as I do neither get crashes when running the code with the USB-2402-UI in LabVIEW 2020 32bit I asssume that there is a bug in one of the two 64bit-dll's "ULx_LV(2.27.0.0)" or "Universal Library™ 6.73". Due to this I conclude that the buggy code piece is USB-2402-specific and, from the observed behaviour, I speculate that maybe at one location in the dll-code memory allocation is done for a 32bit pointer instead of the 64bit pointer used. In consequence, LabVIEW crashes sometimes after 3 for-loop iterations, sometimes after 5 or 7 - and these crashes are absent in the 32bit-version. As I need 64bit due to large datasets coming from a camera in the same instrument and as the bug should be easy to reproduce I hope that MCC will correct this bug soon such that we do not have to search for alternative AD-hardware.
