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

I looked into this, and it does seem like `remove_id` was never implemented for `usb-serial`. Should be able to take the work in `drivers/usb/core/driver.c` and implement `remove_id` in `drivers/usb/serial/bus.c`.

Sorry for not having an easy answer.
