I have an USB device that the kernel does not automatically recognise as an USB serial device but when I manually say to the usbserial driver that it should bind to it (modprobe usbserial vendor=0x0421 product=0x069a), it provides to USB serial interfaces where useful things can be done over it.

What is the right place (email-address, bug tracker, …) to report it to the correct Linux subsystem maintainers to include that device for automatic binding?

The kernel documentation for the generic USB serial driver suggests contacting its maintainer, Greg Kroah-Hartman, directly. See the linked file for the email address to use.

However, loading the usbserial driver produces a log message indicating what should be done:

The "generic" usb-serial driver is only for testing and one-off prototypes. Tell [email protected] to add your device to a proper driver.

So you should send an email to that address with your device ids and a description.

(Interested readers may want to know that this was done both by email and in the kernel bug tracker, and led to a patch which was merged in 5.18.)
