Delay 1.0 where?
It looks like a bug in USB stack.
Line 96:
PS: That’s work in progress, Some procedures don’t work and I’m not sure I’ll keep the current way of handling errors.
The delay has been removed and replaced with if USB_Serial.List_Ctrl_State.DTE_Is_Present then before each Read and Write.
I have however a new problem: I can’t send more then a 32 characters at a time. The USB limit is 64 so I wonder hat is problem here.
