I previously followed the answer in this question: Attaching USB-Serial device with custom PID to ttyUSB0 on embedded
Now, I need to revert that step so that the device id I echoed to new_id doesn't map to ttyUSB0 every time I connect it. The file, new_id, seems to have '0403 e0d0' permanently written to it now. I've tried to use the unbind file to no luck. There's also no "remove_id" file. Only bind, new_id, uevent, and unbind.
How can I revert this?
