Device misdetected as serial mouse

Question

I\'m working on a device which communicates with a PC through a (virtual) serial port. The problem is that the data we are sending occasionally gets incorrectly identified b

Answer 1

If you have a "true" serial port, or an USB dongle (RS-232, RS-485, it does not matter) this problem can be worked around by first opening the serial port in question with a terminal, or whatever application you want to monitor it with, and only then plugging the device in. For your own sake, you should also pay attention to remove the device before terminating the connection.

With FTDI chips soldered on the device itself, you are busted. It took a few rounds for me to explain the management that a device communicating on it's own paired with an FTDI chip soldered on the PCB meeting Windows computers won't likely pass for user-friendliness, no matter how slick an USB socket may look like on the cabinet... (Thankfully, all these conditions coming together are quite rare and unusual)
