How to remove device id from manually entered usb-serial driver

I previously followed the answer in this question: https://unix.stackexchange.com/questions/67936/attaching-usb-serial-device-with-custom-pid-to-ttyusb0-on-embedded?newreg=77c2eaf90f504613a637a40bd9a095b3 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?
