I face an error in one of my designs: "Device Initialization failed, code=-6" while it works fine in other designs. what is error code -6? Before this error it stated that COM port is used by another application. I removed and connected my FTDI USB2serial and even changed its COM port number but the error remained. When I disable and enable the device again, new error with code -6 was appeared.

So one might work and not the other. With serial port problems it is usually about making sure that drivers are installed and no other application is connecting to the same port. Code -6 is a general error when accessing the port.
