I tried to use proton 3.5.5.5 with CDC USB.
I had no problem with version 3.5.2.7 but If I upgrade the code to 3.5.5.5 it don't run.
this is a very simple code in the old version, when the pic receive some data from com port, it respond with the same data.

the same code compiled with vesrion 3.5.5.5 dont run.
I changed only the row :Declare USB_Descriptor = "CDCdesc.Inc" in : Include "CDC_Descriptor.Inc"
here the code :

Windowd see the virtual com port.
also the serilal com plugin connect to the pic.
If I try to send somthing, it dont receive and the comunication program freeze.
It seems that the program don't pass the USBpoll command.
Were i am wong ? what is my mistake ?
please help me with some suggestion
