Pls helb. Error in output data from device

[MemesClub]

thx for lib. But I don't understand what the problem is. I was able to initialize all my devices by VID and PID. However, when I try to get the data, there is no response. If you force data to be output to the console, then there is: ?????????. When trying to output one of the elements of the array, it always outputs 0.
