K8062 vs vb6

good day to all,
i’m a new user, sorry for my poor english! :frowning:
I’ve a problem with k8062 driver:I’ve made a program (vb6) to drive the usb dmx inteface using the k8062 driver and dll.In develop environment it seen does not work (dmx signal led don’t blink) but when I compile the proget (make EXE file and run it), all work fine.
The same problem i’ve found using K8062DEMO.exe and the related VBP.

Any opion is welcome! :cry:

TNx in advance
